The motor protection relay DHC is a temperature monitoring relay for electric motors. It evaluates the resistance values of the PTC thermistors built into the motor winding. A non-volatile restart lock ensures that the relay remains locked in the event of a power failure, i.e. no uncontrolled restart takes place.
The advantages are high safety through restart lock and closed-circuit current principle. Several sensor resistances can also be connected to a relay. The motor is restarted via an integrated acknowledgment button after the normal temperature has been reached.
