Mersen's Fused Coordination Panelboard is designed to meet requirements defined by the NEC to protect critical power operations. Mersen's Fused Coordination Panelboard can simplify the process in achieving code compliance for designers. 

Selective Coordination

A system that is selectively coordinated will ensure that any fault condition is localized to the nearest overcurrent protective device. This increases system reliability and decreases downtime. Selective coordination is desired for all systems but is also mandatory per NEC for critical circuits:

620.62 – Elevator Circuits

700.27 – Emergency Systems

701.18 – Legally Required Standby Systems

Fused Coordination Panelboard

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.

Surge Protection

In 2014, NEC added article 700.8 which requires that a surge protective device must be installed in or on all new emergency system panelboards. NEC defines emergency systems as legally required systems intended to automatically supply illumination, power and systems essential for safety to human life. MFCP helps easily meet this requirement with the optional built-in Surge-Trap pluggable. Surge-Trap utilizes Mersen’s patented fail-safe TPMOV technology.
