Description
Features
- Engineered with an advanced 10-second time-delay at 500% of its rated current, this 4.5-Amp fuse seamlessly tolerates momentary, high-inrush currents from inductive loads. By absorbing safe, temporary surges without opening, it completely eliminates annoying nuisance trips on industrial control loops, exhaust fans, and pump motors, keeping your manufacturing line running smoothly.
- Operating as an ultimate Low-Peak™ current-limiting device, the LPJ-4-1/2SP cuts off destructive short-circuit energy long before it reaches its peak value. This rapid-response architecture isolates faults instantly, preventing thermal and magnetic damage to fragile PLCs, variable speed drives, and automation sensors, minimizing repair overhead.
- Boasting an extraordinary 300,000-amp AC interrupting rating at 600V (paired with a 100kA DC rating at 300V), this Class J fuse can easily handle extreme electrical energy levels. This ultra-high rating ensures your electrical panelboard or machinery disconnect maintains full compliance with strict NEC® Section 110.10 safety codes, ensuring facility insulation integrity during severe power surges.
- Featuring a compact, rejection-style ferrule footprint measuring just 0.81 inches in diameter and 2.25 inches in length, this component fits perfectly into standard Class J fuse blocks and safety switches. The physical dimensions naturally prevent the accidental installation of lower-rated or incorrect voltage classes, acting as a foolproof physical safety guard during field replacements.
