saves even more time on

installation and maintenance

• Min. 250,000 faultless

operations

• UL recognized

FEATURES

VC power relays are designed

for controlling heavy duty

loads safely:

• Contact gap of 3 mm or more

• 2-point contacts for circuits with

high inrush current

• Large insulation distance

• Materials used in the terminal

and the contact blocks are

flame-retardant

Faston terminal

Reliable compact build:

• Solenoid contact relays (AC

type)

• The lever mechanism and

efficient electromagnet

configuration allow for a

substantially more compact

size

CAUTIONS FOR USE

General Usage Conditions

• Avoid using relays in extreme

VC15(4P) should not be used with a

• Ambient temperature (relative

humidity):

–10C°–40C° (45%–85% RH)

40C°–55C° (45%–75% RH)

(No condensation or freezing)

• Elevation: 2,000 m or less

• Operating circuit voltage fluctuation

range:

environments, such as locations subject

to excessive heat, humidity, dust,

corrosive gases, vibrations, mechanical

shocks, or direct sunlight.

• Avoid using relays in locations where

they could be exposed to rain or water

spray. (Such conditions could cause

malfunctions.)

• As shown in Figure 1, secure the ends

of the mounting plate to the mounting

bracket using 4 mm screws, then snap

the relay into place. To remove the

relay, carefully pry loose the hook of the

mounting bracket with the tip of a

screwdriver, as shown in Figure 2, and

then pull the relay out. (Do not to apply

too much force with the screwdriver to

receptacle tab because the insulation

distance cannot be guaranteed.

3) Insert the receptacle firmly to prevent it

from loosening. Removal requires a

pulling force of 2 to 4 kg, so avoid trying

to remove two at the same time. Make

sure to remove only one at a time.

4) Avoid applying solder to terminals.

• Rated frequency: 50/60 Hz

Notes on relay selection

• Select a relay such that the load

capacity is within the rating of the

solenoid switch.

• At the maximum rated motor capacity,

the product has an electrical switching

durability (service life) of 250,000

operations or more. This is suitable for

consumer and light industrial

applications.

• In certain usage environments

(temperature, humidity, oil mist, etc.),

the service life of the contacts may be

shortened. For applications such as

industrial machinery where the usage

environment is poor, select a model that

provides some performance margin.

Contact your National dealer for

assistance when making a selection.

• These relays are not suitable for

applications such as inching or

plugging.

• Using the wrong coil voltage can cause

the coil to burn out. Particular care

should be taken when selecting the coil

voltage in cases where the main circuit

and operating circuit have different

voltages.

• When choosing a thermal relay, make

sure the current adjustment range is

appropriate for the full load current of

the motor, regardless of the voltage of

the main circuit. Operation cannot be

guaranteed if the motor is outside the

current adjustment range.

• The relays are sealed type units and are

adjusted at the factory. They are not

intended to be disassembled by the

user. It is not possible to replace

individual contacts or coils.

• The minimum usable current is the

approximate lower limit value at which

switching operation is possible at very

small load levels. The actual minimum

usable current may differ depending on

factors such as the usage environment.

Relays should therefore be tested at the

actual load level before use.

Installation notes

Mounting

• Mechanical shocks from being dropped,

etc., can cause malfunctions. Handle

relays with care.

Mounting holes

Figure 2

• When relays are mounted side-by-side

horizontally, the operation indicators are

located on the side. Therefore, they

should be positioned at least 5 mm

apart, as shown in Figure 3. In addition,

when they are mounted side-by-side

vertically, as shown in Figure 4, make

sure to leave sufficient space in

between them to allow insertion of a

screwdriver to remove the mounting

brackets.

Usage precautions

• If there is concern that contact problems

(fusing, open-phase, etc.) or the auto-

reset operation of thermal relays could

cause secondary damage, appropriate

safeguards should be built into the

system.

• Make sure not to confuse the terminal

positions when using relays. The

terminals are marked on the nameplate.

Be particularly careful regarding the

positions of terminal b and the coil

terminal.

• Circuits through which current is flowing

continuously for long periods due to the

operation of the relay, etc., should be

designed so that they are in a non-

excited state when left idle. (Examples

include circuits for emergency lamps,

warning devices, and fault detectors

that reset only in case of emergency

and use terminal b to issue warnings.)

Maintenance and inspection

• Due to the danger of electric shock,

always shut off power when performing

maintenance or inspections.

• Periodically retighten terminal screws to

prevent the possibility of overheating or

fire due to loosening.

• If there is concern that contact problems

(fusing, open-phase, etc.) could cause

secondary damage, perform checks

regularly and replace relays as soon as

any problems are discovered.

• If a thermal relay is tripped, correct the

problem and then lightly press the reset

button to restart operation.

• Plug-in terminal connections

1) When removing a VC relay from the

socket, pull it straight out. Pulling the

relay out at an angle could bend the

plug-in terminals.

2) The receptacles listed in the table

below may be used with relays having

plug-in terminals. However, the
