TF Thermal overload relay 13.0-16.0A Trip class 10A – 1SAZ721201R1047

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 AF09 to AF38 contactors, 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, thereby 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, have a test and stop function as well as a tripped indicator. The current scale of the devices can be sealed. Accessories such as reset buttons and wire resetters complement the range. TF42 have trip class 10, are temperature compensated and phase-failure sensitive, and have Atex approval.
