Bussmann LPJ-40SP 600V AC/300V DC, 40A, Dual Element, Time-Delay Fuse

This time-delay fuse from Bussmann has been designed with an optional open fuse indication on select ratings (see data sheets).

Other features include the separate overload and short-circuit elements, providing time delay for sizing of high inrush loads linked with Class J current limitation, while 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.

* Minimum 10sec time delay at 500% overload * Minimises needless fuse openings due to temporary overloads and transient surges * Provides back-up protection against motor burnout (from overload or single-phasing) * High interrupting rating to safely interrupt overcurrents up to 300,000A * High degree of current limitation due to the fast speed-of response to short-circuits * Faster response to damaging short-circuit currents * Reduces let-through thermal and magnetic forces * Length: 60.5mm * Diameter: 26.9mm * Nominal current: 40A * Nominal voltage: 600V AC * Manufacturer's part LPJ-40SP
