MotorCap P2 Aluminum Can

AC Film Capacitors for Motor Run Applications

For film capacitors, the metalized technology is applied. An extremely thin metal film is

deposited in a high vacuum onto the low-loss polypropylene film. Then two layers of

metalized film are wound to form the electrodes. The impulse resistance is possible

due to the so-called self-healing effect. By using polypropylene as the dielectric, the

capacitors have a particularly low dissipation factor.

AC film capacitors are usable for general sine-wave applications as filters, inverters,

UPS devices etc., but are also particularly suitable for the operation of asynchronous

electric motors and electric compressors. As motor run capacitors, they assure

smooth and energy-saving operation of electric motors used in applications such as

refrigerators, freezers, electric compressors, washers, dryers, air-conditioning appli-

ances, ventilators, pumps, electric doors and drives.

This brochure presents the MotorCap P2 aluminum can capacitors series B32330/

B32332/32333/32335 of EPCOS. The use of MotorCap capacitors increases the

energy efficiency of motors and compressors by up to 12 percent. They also signifi-

cantly improve the torque response of the motor (or compressor). This is important for

motors and compressors in continuous operation. MotorCap capacitors are ad-

dressed particularly to manufacturers of air conditioning systems, washing and drying

appliances, compressors for refrigerators and freezers, but also of general electric mo-

tors for a variety of applications. MotorCap capacitors comply to high safety standards

(UL, VDE, TÜV, CQC).

Important Notes

The following applies to all products named in this 4. In order to satisfy certain technical requirements, some of

publication:

the products described in this publication may contain

substances subject to restrictions in certain jurisdic-

tions (e.g. because they are classed as hazardous).

Useful information on this will be found in our Material

Data Sheets on the Internet (www.epcos.com/material).

Should you have any more detailed questions, please con-

tact our sales offices.

1. Some parts of this publication contain statements about

the suitability of our products for certain areas of ap-

plication. These statements are based on our knowledge

of typical requirements that are often placed on our prod-

ucts in the areas of application concerned. We neverthe-

less expressly point out that such statements cannot be

regarded as binding statements about the suitability 5. We constantly strive to improve our products. Conse-

of our products for a particular customer application.

As a rule, EPCOS is either unfamiliar with individual cus-

tomer applications or less familiar with them than the

customers themselves. For these reasons, it is always ul-

timately incumbent on the customer to check and decide

whether an EPCOS product with the properties described

in the product specification is suitable for use in a partic-

ular customer application.

quently, the products described in this publication

may change from time to time. The same is true of the

corresponding product specifications. Please check

therefore to what extent product descriptions and speci-

fications contained in this publication are still applicable

before or when you place an order.

We also reserve the right to discontinue production

and delivery of products. Consequently, we cannot

guarantee that all products named in this publication will

always be available.

2. We also point out that in individual cases, a malfunc-

tion of electronic components or failure before the

end of their usual service life cannot be completely

ruled out in the current state of the art, even if they are

operated as specified. In customer applications requir-

ing a very high level of operational safety and especially in

customer applications in which the malfunction or failure

of an electronic component could endanger human life or

health (e.g. in accident prevention or life-saving systems),

it must therefore be ensured by means of suitable design

of the customer application or other action taken by the

customer (e.g. installation of protective circuitry or

redundancy) that no injury or damage is sustained by third

parties in the event of malfunction or failure of an electron-

ic component.

The aforementioned does not apply in the case of

individual agreements deviating from the foregoing for

customer-specific products.

6. Unless otherwise agreed in individual contracts, all

orders are subject to the current version of the “Gen-

eral Terms of Delivery for Products and Services in

the Electrical Industry” published by the German

Electrical and Electronics Industry Association (ZVEI).

seconds. The gas pressure caused at

this spot by the high temperature

blows the metal vapour away of the

breakdown region. This means that a

non-conducting isolation region free

of metalization is formed here.

During and after the breakdown the

capacitor is fully functional. The re-

duction in capacitance caused by

self-healing is less than 100 pF, i.e. of

an order that can only be verified by

a precision measuring instrument.

Innovations and Advantages

MotorCap P2 aluminum can protection via overpressure disconnection device

Overpressure protection with a

break-action mechanism:

MotorCap P2 aluminum can

P2 definition according

IEC/EN 60252-1 and UL 810

Construction

Electronic components do not have

unlimited life expectancies. This applies

to self-healing capacitors, too. Motor

run capacitors of the series B32330/

B32332/B32333/B32335 are conven-

tionally constructed as aluminum cans

with class P2 safety protection. They

are fitted with a disconnector that

responds only to overpressure. Numer-

ous electric breakdowns over time or

as result of thermal or electric overload

result in the formation of gas, which

can cause the pressure to rise inside

the capacitor case. This produces a

change in length due to the curvature

of the lid or stretching of the expansion

bead. Expansion beyond a certain

degree will separate the internal wires

and disconnect the capacitor from the

line. This disconnection takes place at

a defined position (notch) after a total

baffle expansion of 0.3 to 1.6 mm,

depending on the size of the capacitor.

To prevent case rupture under fault

conditions, the capacitor has been

designed to fail in the open-circuit

mode only. It is protected against fire

and electrical shock hazards.

Applications

Operation

Requirements of IEC 60335-1

The approval is granted for the com-

plete capacitor assembly and not for

individual raw materials only.

The MotorCap P2 aluminum can

capacitor is simply plugged into the

auxiliary winding of the motor or com-

pressor and can remain permanently

connected there. The capacitor is

designed for continuous operation.

Domestic appliances are subject to

the IEC 60335-1 standard. If a motor

run capacitor is used in a domestic

appliance that is subject to this

standard, there may be additional

requirements on the capacitor.

The materials as well as the creepage

and clearance distances selected for

the EPCOS MotorCap P2 aluminum

make it ideal for use in domestic

appliances.

Applications

These refer essentially to the materi-

als used as well as to the creepage

and clearance distances.

The MotorCap P2 aluminum can

was optimized for use in the follow-

ing applications, but may be used

equally well for general drive motors.

Cautions and Warnings

¼

The MotorCap P2 aluminum can should be operated in

line with its typical approved usage.

Observe the appropriate engineering practice.

The capacitor terminals, connected busbars and cables

as well as any other devices connected to them must

be regarded as live. The device is electrically charged.

Handle the capacitor units carefully, as they may be

charged even after disconnection.

Storage and operating conditions

Installation

Do not use or store capacitors in a corrosive atmosphere,

especially where chloride gas, sulfide gas, acids, alkalis,

salts or similar substances are present. In a dusty environ-

ment, regular maintenance and cleaning, especially of the

terminals, is required to avoid formation of a conductive

path between phases and/or phases and ground.

Mounting orientation

Motor-run capacitors may be mounted in any orientation.

However, the capacitor is preferentially mounted with its

terminals facing upwards.

Preferential

orientation

Ambient temperature

The capacitor must not be exposed to direct heat or fire.

The permissible range of minimum and maximum tempera-

tures is specified on the capacitor i.e.

25/70/21 = minimum permissible temperature: –25 °C,

max. permissible temperature: +70 °C.

25/85/21 = minimum permissible temperature: –25 °C,

max. permissible temperature: +85 °C.

V In case of dents deeper than 0.5 mm, do not install

Temperature is one of the main stress factors for poly-

propylene type capacitors. It has a major influence on their

useful operating life. It should be noted that this useful life

is considerably shorter in the case of higher temperature

requirements. If the maximum permissible temperature is

exceeded, the safety device may become inoperative.

the capacitor.

Fixation

Motor-run capacitors must be installed in a cool and well-

ventilated place away from objects radiating heat. The maxi-

mum torque of capacitors with an M8 bolt is 5 Nm. This

bolt is used for grounding the aluminum case. If the capaci-

tor is fixed with a clamp, make sure this does not block or

disable its safety device.

V Do not expose the capacitor to a direct heat source!

Direct exposure or proximity to heat sources can create

hot spots on the capacitor much hotter than the ambient

temperature and can cause sudden internal failures.

Operating voltage V_op

The capacitors have been designed for continuous opera-

tion at the rated voltage stated on the label. This voltage

may be exceeded only within the limits permitted by the

applicable standards at room temperature:

Cautions and Warnings

Connectors

Overpressure disconnector

In case of fast-on terminals, the female connectors must

be appropriate for the terminal. A good contact must be

ensured.

Electrical components do not have an unlimited operating

life; this also applies to self-healing capacitors. All capacitors

of the B32330, B32332, B32333 and B32335 series are

consequently fitted with a disconnector that responds to

overpressure. If numerous electrical breakdowns occur at

the end of the capacitor’s operating life or as a result of

thermal or electrical overload, the formation of gas increases

the pressure inside the capacitor case.

Do not solder cables directly onto the fast-on terminals.

The terminal may overheat, the capacitor may leak and any

safety device will not operate properly.

V If the female connector becomes loose, the terminal

may overheat, the capacitor may leak and any safety

device will not operate properly.

This causes the expansion bead to expand. If it does so

beyond a certain point, the internal wires will separate (tear-

off fuses) and disconnect the capacitor from the line open-

ing at a predefined position (notch) at an expansion of 0.3

to 1.6 mm, depending on the capacitor size. This safety

mechanism is irreversible. Once the safety device has

operated, the capacitor will remain switched off. Because

the notch of the mechanical safety mechanism is the

weakest section in the connection, P2 aluminum capacitors

should be handled properly during transportation to avoid

damaging the break-action mechanism.

The hermetic seal of the capacitor is extremely important

for a long operating life and correct functioning of the

break-action mechanism of the overpressure disconnector.

Do not damage the rubber seal and the soldering at the

tab connectors. The safety feature of the capacitor may not

function properly if the capacitor is short-circuited across

the terminals. Sufficient precautions must be taken when

connecting the capacitor.

Harmonics

Harmonics are sinusoidal voltages and currents whose

frequencies are multiples of a 50 Hz or 60 Hz power supply

frequency. They result from the operation of electrical loads

with non-linear voltage-current characteristics. These loads

are largely associated with modern electronic devices such

as converters, electrical drives, welding machines and

uninterruptible power supplies (UPS).

In normal condition

Safety device

activated

Harmonics may cause a higher than rated current to flow

through the capacitors, which may overheat and become

damaged. This may cause operational failures, bursting

and fire.

The maximum permissible current (incl. fundamental and

harmonic currents) specified in the technical data of

the relevant series must not be exceeded under any

circumstances.

Maintenance

There are no serviceable or repairable parts inside the

capacitor, so please refrain from opening it.
