Syncrocloser® Check Relay


Secure reclosing of a circuit breaker

The M-0388 Syncrocloser® Check Relay is used as a permissive relay for secure reclosing of a circuit breaker by verifying that voltage and phase angle conditions are within pre-set limits before allowing the breaker to close. It is a panel-mounted, direct mechanical replacement for G.E. IJS and SLJ, and Westinghouse CVE relays.

  • Panel mounted G.E. IJS and SLJ or Westinghouse CVE replacement.

  • Accurate, independent phase, time and voltage functions

  • Transducer and status outputs are standard features

  • Modular construction allows cards to be removed while unit is installed

  • Optional unit with voltage checking and dead line and dead bus closure capabilities can be installed at any time.

  • Does not require a separate power source

  • Complete test and checkout from front panel

  • 20A output relay contacts open 0.9A inductive as 125V dc

  • Temperature range of -40° to +80° C
