STDT 16 Motor Protection

Art. no.: 5152

Thermal contact motor protection

The STDT 16E (for rail mounting) and the STDT 16 (for wall mounting) switch off the supply voltage to the motor when the thermal contact in the motor windings is tripped. The motor protector is connected to a 400V supply and also to the thermal contact in the motor.

The motor protector is reset by pressing the black button as soon as the motor windings have cooled sufficiently. The motor protector can also be used in conjunction with a transformer. Manually turn on and off with connected motors possible. An alarm contact (K) is available as an accessory. The alarm contact has an integral potential-free contact producing an external signal when the relay has been tripped.
