Information About LPJ-250SP
The LPJ-250SP is a 250-amp, dual-element, time-delay Class J fuse from Eaton Bussmann’s Low-Peak® LPJ-SP series, designed to deliver superior short-circuit and overload protection in industrial and commercial power systems. With a 600 V AC / 300 V DC rating and up to 300 kA interrupting capacity, this fuse is ideal for motor circuits, lighting panels, branch circuits, and transformers where high inrush currents and coordination with downstream devices are critical.
Key Features:
- 250 Amp Time-Delay Fuse: Withstands harmless overcurrent surges during motor start-up or transformer energizing.
- Dual-Element Construction: Allows reliable separation of short-circuit and overload protection.
- Class J Rated: Compliant with UL 248-8, compatible with all Class J fuse holders.
- High Interrupting Rating:
- 300 kA RMS Symmetrical at 600 V AC
- 100 kA at 300 V DC
- Current-Limiting: Limits fault current energy, reducing potential damage to wiring and equipment.
- Compact Blade-Style Form: Fits into tight panel layouts; quick installation and replacement.
- Agency Approvals: UL Listed, CSA Certified, CE Marked, RoHS Compliant.
The LPJ-250SP fuse offers robust protection and high-performance circuit safety for a wide range of critical electrical applications. Its time-delay functionality, high interrupting ratings, and compliance with modern safety standards make it a trusted solution for both OEMs and maintenance engineers.
