Thermal overload relays are electromechanical Protection devices for the Power circuit. They offer Reliable Protection for motors in the event of overload or phase failure. The thermal overload relays are 3 poles relays with bimetal tripping elements. The motor current flows through the bimetal tripping elements and heats them directly and indirectly. In case of an overload (over current), the bimetal elements bend as a result of the heating. This leads to a release of the relay and a change of the contacts switching Position (95-96 / 97-98).Economic overload ProtectionAutomatic and manual ResetReset, test and stop functionsDirect contactor mounting up to 200 AMotor applications up to 310 ATest function and On-Off status indicationTerminals 1/L1, 3/L2, 5/L3 for direct mounting to contactorsTA-Relays are temperature compensated between -25 to 55 deg C
