TCMOV Varistor Series

Description

The LittelfuseTCMOV is a thermally self protected device. It

consists of a 34mm varistor with an integral thermal disconnect

system designed to open in the event of overheating due to

abnormal over-voltage conditions, outlined in UL 1449. TheTCMOV

helps facilitate SPD module compliance to UL1449 for type 1 and

type 2 applications.

The device integrates a micro-switch which is triggered by a

mechanical structure that makes the indicator circuit isolated from

the main power. If the device disconnects from the system power

the switch will change status. These features simplify the design

and save cost for the customer.

TheTCMOV devices offer quick thermal response due to the close

proximity of the integrated thermal element to central section of

the MOV body. This conﬁguration also offers lower inductance

than most discreet solutions resulting in improved clamping

performance to fast over-voltage transients.

UL 1449

Rated AC Voltage (V_M(AC)RMS) – MCOV

An Underwriters Laboratory standard covering the safety

requirements for Surge Protective Devices intended for

permanently connected, cord-connected and direct plug-in

applications.

ThisꢀisꢀtheꢀmaximumꢀcontinuousꢀsinusoidalꢀRMSꢀvoltageꢀ

that may be applied. This voltage may be applied at any

temperature up to the maximum operating temperature of

the device.

SCCR

Maximum Non-Repetitive Surge Current (I_TM

)

The suitability of an Surge Protective Device for use on an

AC power circuit that is capable of delivering not more than

a declared rms symmetrical current at a declared voltage

during a short circuit condition.

This is the maximum peak current which may be applied

forꢀaꢀsingleꢀ8/20µsꢀimpulse,ꢀwithꢀratedꢀlineꢀvoltageꢀalsoꢀ

applied, without causing device failure. The pulse can

be applied to the device in either polarity with the same

conﬁdence factor.

Maximum Non-Repetitive Surge Energy (W_TM

)

This is the maximum rated transient energy which may be

dissipated for a single current pulse at a speciﬁed impulse

duration,ꢀwithꢀtheꢀratedꢀRMSꢀvoltageꢀapplied,ꢀwithoutꢀ

causing device failure.

Nominal Discharge Current (I_N)

Peak value of the current, selected by the manufacturer,

throughꢀtheꢀSPDꢀhavingꢀaꢀcurrentꢀwaveshapeꢀofꢀ8/20µsꢀ

where the SPD remains functional after 15 surges.

Voltage Protection Rating (V_PR

)

Nominal Voltage (V_N(DC)

)

A rating selected from a list of preferred values as given

in UL 1449 and assigned to each mode of protection. The

valueꢀofꢀVPRꢀisꢀdeterminedꢀasꢀtheꢀnearestꢀhighestꢀvalueꢀ

taken from UL 1449 to the measured limiting voltage

determined during the transient-voltage surge suppression

test using the combination wave generator at a setting of

6kV, 3kA.

This is the voltage at which the device changes from the

offꢀ(standbyꢀstate)ꢀtoꢀtheꢀonꢀ(clampingꢀstate)ꢀandꢀentersꢀ

its conduction mode of operation. The voltage value is

usually characterised at the 1mA point and has a speciﬁed

minimum and maximum voltage range.
