Secure reclosing of a circuit breaker

The M-0390 Syncrocloser¨ Check Plus 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. The M-0390 uses phase angle/slip frequency to verify synchronism to provide rapid restoration with the smallest possible angle settings. It is a panel-mounted, direct upgrade 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, voltage and delta F functions
• Transducer and status outputs are standard features
• Modular construction allows cards to be removed while unit is installed
• Dead line/dead bus close capability is standard
• 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
