RS PRO Phase Monitoring Relay, Three Phase, 150 to 260V ac

The RS PRO phase failure relay which is also known as phase protection relay prevents three-phase motor failure due to line or motor overheating. The relays are designed to protect the devices with sensitive operation voltage against failures due to line voltage. It is important to remember that phase failure relays do not ensure direct protection.

Why Would You Choose This Relay?

This monitoring relay only detect abnormalities such as excessive voltage, low voltage, inverse phase order or phase drop. Then, the relays send a signal to the circuit breaker components. Thus, the phase failure relays help the healthy operation of the motor and increase system efficiency. They prevent any disruption due to failures and decrease the electrocution or fire risks. This product is used with three phase systems, with neutral.
