Bussmann LPJ-40SP Class J Dual-Element Time-Delay Fuse

Bussmann Low-Peak Class J Dual-Element Time-Delay Fuse, 40A 600VAC

The Bussmann Low-Peak Class J fuse is a dual-element, time-delay fuse engineered for reliable overcurrent protection in demanding electrical systems. Rated 40-Amp at 600-Volt AC and 300-Volt DC, this Class J fuse delivers current-limiting performance in a non-rejection body style. Its dual-element design combines fast-acting short-circuit protection with time-delay response to handle motor inrush and other temporary overload conditions without nuisance opening. Low-Peak LPJ-series fuses are widely specified for motor circuits, feeders, and branch circuits where both AC and DC voltage protection may be required. The dual-rated 600-Volt AC and 300-Volt DC construction gives installers flexibility across a range of system voltages while maintaining consistent current-limiting performance.

Key Features

• Amperage Rating: 40-Amp rating suited to circuits requiring this specific overcurrent threshold.
• Voltage Rating: Rated 600-Volt AC and 300-Volt DC for use across both AC and DC power distribution systems.
• Class J Construction: Low-Peak Class J design delivers current-limiting performance, reducing peak let-through current and energy during fault conditions.
