Coordinated overload protection

Mersen’s Fused Coordination Panelboard (FCP) provides a simple 2:1 coordination ratio with upstream Amp-Trap 2000 fuses, eliminating the need for a costly short circuit current study. 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. Mersen’s FCP is a UL67 listed panelboard that utilizes commonly available class CC and J fuses. Combination rated circuit breaker and fuse for branch circuit protection ensures fuses will open only on short- circuits and the circuit breaker can easily be reset on common overloads. The circuit breaker is designed to operate on overloads up to 2 times their rating and the fuse over 2 times up to 200kA.
