Features and Benefits

? Separate overload and short-circuit elements provide time

delay for sizing of high inrush loads linked with Class J

current limitation.

? Selective coordination ratio of 2:1 (within Low-Peak fuse

family) prevents electrical shutdowns from extending

beyond the failed circuit.

? Series combination ratings with branch circuit breakers

allows broad range of coverage, independent of breaker

manufacturer.

Typical Applications

? Power Panelboards

? Branch Circuit Breaker Panelboard Mains

? Machinery Disconnects

? Industrial Control
