Fused Coordination Panelboard

The next generation of Fused Coordination Panelboards is here with coordinated protection between overloads and short circuits
The next generation of Fused Coordination Panelboards is here with coordinated protection between overloads and short circuits

  • 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 fuse. The circuit breaker is designed to be resettable on operations for overloads and operate the series fuse for faults up to 200kA. Mersen’s Fused Coordination Panelboard can simplify the process in achieving code compliance for designers. 

    The  Product Configuration and Selection Tool allows Mersen partners to design their own custom-configured panelboard by selecting the ratings, features, and options you want via a graphical interface or selection of features. The Configuration tool will also provide a detailed quote and in of the job in PDF format. Mersen specialists can also work with you to design a solution that fits your requirements.

  • Benefits

    Mersen’s Fused Coordination Panelboard (MFCP) does not require fuse replacement on common overload conditions and branch circuits can simply be reset. Mersen’s Amp-Trap 2000® class CC and class J fuses ensure minimal fuse let-thru energies and makes it easy to provide system coordination with our easy 2:1 coordination ratios for short circuits.

    Mersen’s fused selective coordination panelboard is a UL67 listed panelboard that utilizes our commonly available class CC and J fuses.

    • Circuit Breaker trips instead of Fuse opening with 2X rating
    • Mersen Panel is UL listed to accept any manufacturer’s Class CC and J fuse
    • Class CC and J fuses are commonly stocked
    • Load Connections UL Listed for 2 wires to help with Inspection during last-minute changes
