FR95: Frequency Relay
FR95 "WISCO" Frequency Relay
- Over-under frequency Protection
- Output relay SPDT, 250V, 3A
- LED indicate relay status
- Signal output for panel meter display
The Frequency Relay FR95 is designed to monitor the system frequency. When the frequency moves outside the setpoint limit the relay will operate giving an alarm or tripping signal. Since speed is propotional to frequency, it can be used to protect A.C. generator plant against overspeed or underspeed.
