Agency Information: CE, UL Listed - Special Purpose*,

Guide JFHR, File E56412, CSA Certified (200k AIR) Class J

per CSA-22.2 No. 248.8, Class 1422-02, File 53787.

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
