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.
