Product Details

45UFR Frequency Relay

This Broyce Control 45UFR electrical relay unit is designed to monitor the frequency of its own supply. The 45UFR is used for monitoring under frequency conditions, whereby the relay de-energises when the frequency drops below the adjustable trip point. The relay re-energises when the frequency increases above the trip point plus the hysteresis.
