Mersen's Fused Coordination Panelboard

Selective Coordination is required in several locations as defined in the National Electrical Code® (NEC). Mersen’s Fused Coordination Panelboard (MFCP) can simplify the process in achieving code compliance for designers. These panels are provided with a default short circuit current rating (SCCR) of 200kA and provide overcurrent protection through a combination of a circuit breaker and a fuse. The circuit breaker is designed to operate on overloads up to 2 times their rating and the fuse will operate for faults over that value, and up to 200kA.
