Fused Coordination Panelboard

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.
