Monitoring relay for motor temperature monitoring. Temperature monitoring of the motor winding with fault latch with self-reset.
Monitoring relays RPN-1AT-A230
Relay for motor temperature monitoring. 12 A, supply voltage 230 V AC. Monitoring relays with fault latch and self-reset (with delayed connection/disconnection of contact R).
Technical info
Temperature monitoring of the motor winding with fault latch with self-reset. When the total resistance of the PTC circuit exceeds 3,6 kΩ (temperature increases), the operational relay R will be disconnected. The operational relay R will be switched back on when the total resistance of the sensors falls below 1,65 kΩ (the system is cooled).
