Tender text

PTC thermistor triggering relay for switch cabinet installation (1 device per motor required). The thermistor overload relays monitor motors which are equipped with PTC thermistor temperature sensors. The temperature sensors are installed in the windings of the motors and measure the heating up of the motor directly. This enables direct monitoring and evaluation of various operating conditions. A collective fault signal (SSM) is possible with corresponding wiring in the switch cabinet.
