Telect's 600CB08 and 600CB10 power panels support mid-trip breakers which indicate when a circuit breaker has been tripped versus just shut off.  Using a mid-trip breaker prevents alarms being generated when a circuit is shut-off for maintenance.  The P/N 127881 is a mid-trip 60A breaker, where the P/N 118160 is a standard 60A breaker.  Either breaker can be used in the Telect panels.
