Further Details:
The thermal overload relays TA200DU provide reliable protection for connected motors for currents up to 200 A, in accordance with IEC/EN 60947-1, IEC/EN 60947-4-1, and IEC/EN 60947-5-1. TA200DU can be directly mounted on contactors AF190-AF205, but can also be mounted separately on a mounting plate. Thermal overload relays are three-pole and trip via bimetallic elements. The motor current flows through the bimetallic elements, heating them both directly and indirectly. In the event of an overload (overcurrent), the bimetallic elements deform due to the heat generated. This causes the relay to trip, changing the switching positions of the contacts (95-96/97-98). A preceding contactor can thus be switched off. The relays allow for manual or automatic resetting, and they feature test and stop functions as well as a tripped indicator. An additional reset button allows operation without opening the control cabinet. TA200DU have a tripping class of 10A, are temperature compensated, and are sensitive to phase failure.
