RS PRO Phase Monitoring Relay, Three Phase, 380V ac, DIN Rail

The RS PRO phase failure relay, also known as a phase protection relay, is an essential safeguard for three-phase motors, preventing failures caused by line issues or motor overheating. Designed to protect voltage-sensitive devices, it detects critical anomalies such as excessive or low voltage, phase drop, and incorrect phase order.
While the relay itself doesn’t provide direct protection, it acts as a vigilant monitor, promptly signalling circuit breaker components to act. By ensuring smooth motor operation and maintaining system efficiency, the RS PRO phase failure relay minimizes downtime, prevents disruptions, and reduces the risks of electrocution or fire.
Engineered for three-phase systems without a neutral, this relay is a reliable solution for keeping your operations running safely and efficiently.
