Metz Connect Monitoring relay 230 V AC (max) 1 change-over Metz Connect 1 pc(s)

The thermistor relay is used as a protection relay for motors against thermal overload (inadmissible heat-up). This warming may occur due to mechanical overload on the shaft or when operating the motor with unacceptable voltages. A PTC (PTC) is used as a sensor, which is placed as far as possible at the part of the motor which heats up most when overloaded (e.g. integrated in the motor winding). The device is also applicable in motors with which a thermo switch is integrated. Integrated fault memory with front reset button or connection of an external reset button (terminals B1 - B2)., variants:, 230 V AC or 24 V AC/DC, 1 changer or 2 changer.
