The PTC-resistor relays in

combination with our PTC

thermistors ensure cost-effective

and reliable thermal overload

protection of electrical machines.

Our PTC-resistor relays can be used in conjunction with all PTC sensors according to DIN 44081/44082 for direct temperature monitoring of motors. The switching point of the monitoring device is determined by the nominal response temperature (NAT) of the PTC thermistors. Various types and voltage variants are available.
