Bussmann LPJ Low-Peak Class J Dual-Element Time-Delay Fuse

Bussmann LPJ Low-Peak Class J Dual-Element Time-Delay Fuse

The Bussmann LPJ Low-Peak Class J fuse family delivers dual-element, time-delay overcurrent protection for demanding electrical systems. This family is available in amperage ratings from 20A to 40A, all sharing a dual voltage rating of 600VAC/300VDC and a non-rejection Class J body style. The dual-element design combines fast-acting response to short-circuit currents with time-delay characteristics that ride through motor starting inrush and temporary overload conditions without nuisance opening. Low-Peak LPJ-series fuses are widely specified for motor circuits, feeders, and branch circuits where reliable, current-limiting protection is required across both AC and DC power distribution systems. Whatever amperage you select from the 20A-40A range, you get the same Class J current-limiting performance and dual-element construction that Bussmann Low-Peak fuses are known for.

Key Features

• Amperage Range: Available in 20A, 35A, and 40A ratings to match a variety of circuit overcurrent thresholds.
• Voltage Rating: Rated 600VAC/300VDC 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.
• Dual-Element Time-Delay: Combines fast response to short-circuit currents with time-delay characteristics that ride through motor starting and temporary overload currents without nuisance opening.
• Non-Rejection Body Style: Non-rejection configuration for compatibility with standard fuse holders and fuse clips.
• Current-Limiting Performance: Limits let-through current and energy to help protect downstream conductors, components, and connected equipment across the entire LPJ amperage range.
• Series: Part of the Bussmann Low-Peak (LPJ) product line engineered for high-performance current-limiting protection.
• Application Versatility: Suited for motor branch circuits, feeders, and other circuits requiring Low-Peak current-limiting protection at 20A, 35A, or 40A.
