Information About LPJ-125SP

The Eaton LPJ-125SP Bussmann Low-Peak Fuse is a high-performance component from the LPJ Series, designed to provide reliable overcurrent protection in industrial and commercial applications. This current-limiting, time-delay fuse operates at 600 VAC and 300 VDC with a current rating of 125 A, making it suitable for a variety of power distribution systems.

The LPJ-125SP is a non-indicating, non-rejection Class J fuse, providing dependable protection without additional indication features. It boasts a high interrupt rating of 300 kAIC at 600 VAC and 100 kAIC at 300 VDC, ensuring robust fault current handling capabilities.

This dual-element fuse features a time-delay response of 10 seconds at 500% of the rated current, allowing for temporary inrush currents and providing reliable protection against both short circuits and prolonged overloads. The fuse is equipped with bolted blade end terminals for secure connections and is designed for holder mounting, ensuring ease of installation and maintenance.

Constructed with a durable melamine cartridge body, the LPJ-125SP measures 1.63 inches in diameter and 5.75 inches in length, making it compact yet robust for demanding applications. The use of melamine enhances the fuse's ability to withstand high temperatures and electrical stresses.

In summary, the Eaton LPJ-125SP Bussmann Low-Peak Fuse offers superior protection with its high interrupt rating, time-delay characteristics, and durable construction, making it an ideal choice for safeguarding electrical systems in industrial and commercial environments.

Features
Separate overload and short circuit elements provide time delay for sizing of high inrush loads linked with class J current limitation
Selective coordination ratio of 2:1 (within Low-Peak fuse family) prevents electrical shutdowns from extending beyond the failed circuit
Series combination ratings with branch circuit breakers allows broad range of coverage, independent of breaker manufacturer
Proper sizing can provide "no damage" type 2 co-ordinated protection for NEMA and IEC motor controllers
Space saving package for equipment downsizing
Industrys only UL listed and CSA certified fuse with a 300 kA interrupt rating that allows for simple, worry-free installation in virtually any application
Fast short circuit protection and dual element, time delay performance provide ultimate protection
Reduces existing fuse inventory by up to 33% when upgrading to Low-Peak fuses
Consistent 2:1 ampacity ratios for all Low-Peak fuses make selective co-ordination easy
Long time delay minimizes needless fuse openings due to temporary overloads and transient surges
Current limitation protects downstream components against damaging thermal and magnetic effects of short circuit currents
Dual element fuses have lower resistance than ordinary fuses so they run cooler
They can often be sized for back up protection against motor burnout from overload or 1 ph if other overload protective devices fail
