When the conditions for an arc short circuit occur
(simultaneous overcurrent and arc signal), the master unit
trips the circuit-breaker(s) of the incoming feeder(s). A master
unit can trip up to four circuit breakers. If more than four
parallel trip outputs are required, the trip multiplier relay VAR
4 CE can be used.
