Ferraz Shawmut panel helps implement selective coordination
Ferraz Shawmut introduces the Fused Selective Coordination Panel. Recent National Electrical Code (NEC) changes require selective coordination in a number of critical circuits. Selective coordination forces the protective device nearest to a fault to trip before any upstream protective device, ensuring that critical loads connected in parallel to the fault are not interrupted. This can be accomplished with circuit breakers or fuses, but fused solutions provide the easiest ways to implement and maintain selective coordination during the life of the installation. Fused solutions are more cost effective and provide selective coordination with 2:1 ratios, using Ferraz Shawmut Amp-Trap 2000 fuses. The use of fuses in the panel also provides a higher short circuit current rating (SCCR), compared to that of a typical circuit breaker panel, which the market demands.
Each Ferraz Shawmut Fused Selective Coordination Panel is a UL67-listed panelboard that uses class CC Ultrasafe fuse holders with easy-to-see blown fuse indicators. The compact size and removable backpan allow for easier installation by contractors. Features of the panel include a bonded ground bar and a neutral bar with set-screw terminations. MLO (main lugs only) terminations include an optional molded case switch. Branch circuit breakers provide circuit isolation, and the panel comes with a 100A, 200A or 300A copper main bus. The panels accommodate 12 to 42 circuits.
