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.
