      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.

      Detects Under frequency
      UFR relay de-energises if frequency falls below trip level – red LED on, contacts 11, 14 /21 & 24 closed
