TF42 are economical, electromechanical motor protection devices for currents up to 38 A. In the event of an overload, they provide reliable thermal protection for the connected motors. TF42 are normally mounted on contactors AF09 to AF38, but the devices can also be mounted separately on a DIN rail using a single mounting kit. If the motor current set on the current scale is exceeded, the relays trip via bimetallic elements, thus changing the switching position of the two auxiliary contacts 1NO/1NC. A upstream contactor is thus switched off. The relays allow manual or automatic reset, they have test and stop functions as well as a tripped indicator. The current scale of the devices can be sealed. Accessories such as reset buttons and wire remote resetters complement the range. TF42 have trip class 10, are temperature compensated and phase failure sensitive and have Atex approval.
