Fused Coordination Panelboards

Mersen Fused Coordination Panelboards WebLink

Mersen’s Fused Coordination Panelboard is designed to meet requirements defined by the National Electrical Code (NEC) to protect critical power operations. 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 over 2 times up to 200kA. Mersen’s Fused Coordination Panelboard can simplify the process in achieving code compliance for designers.

The breaker offers customers a re-settable overload device when providing fuses for short circuit protection. We size the breaker to trip on overloads saving the customer from having to replace the fuse when overloads occur. 

Achieving selective coordination typically requires a costly short circuit current study. However with the Mersen Fused Coordination Panelboard, coordination can easily be determined with upstream Mersen fuses.
