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.
