Description
Features
- Engineered with an advanced current-limiting design, this Class J fuse rapidly isolates high-magnitude short circuits before they can unleash catastrophic thermal and magnetic forces. By strictly limiting peak let-through current, it acts as a premier protective shield for sensitive solid-state components, industrial control panels, and branch circuits.
- Featuring a true dual-element build, this fuse delivers a minimum 10-second time-delay at 500% of its 1.25-amp rating. This allows it to absorb heavy, temporary in-rush currents and transient motor surges seamlessly, cutting down on costly downtime caused by needless fuse openings while maintaining ultimate overcurrent protection.
- Boasting an exceptional 300 kA AC and 100 kA DC interrupting rating, it provides worry-free installation across high-capacity industrial power systems. This massive breaking capacity ensures safe fault isolation in virtually any application, effortlessly matching or exceeding strict compliance mandates.
- This non-rejection, ferrule-terminal cartridge measures a standardized 0.81 inches in diameter by 2.25 inches in length. Its compact, space-saving design permits industrial equipment downsizing and drops directly into standard Class J fuse blocks or modular disconnect switches without any structural retrofitting.
- Offering a consistent 2:1 ampacity ratio within the Low-Peak family, this fuse makes complex selective coordination simple and predictable independent of breaker manufacturers. If a fault occurs, only the fuse closest to the issue opens, preventing widespread cascading blackouts across your facility's electrical infrastructure.
- This specialized component is fully UL Listed and CSA Certified, assuring compliance with rigorous global safety and electrical codes. Additionally, its dual-element engineering boasts a lower internal resistance than ordinary fuses, allowing it to run cooler and provide robust Type 2 "No Damage" backup protection for NEMA and IEC motor controllers.
