LPJ-125 SP Bussmann Low-Peak Dual-Element Time-Delay Class J Fuses Rated 125 Amp 600 Vac / 300 Vdc Current Limiting Ultimate Protection Fuse Rated up to 300kA Vac Interrupting Rating (
Equal to AJT, JTD, JDL )
Ultimate protection Class J dual element, current-limiting, time-delay fuses. Time-delay = 10 seconds (minimum) at 500% of rated current.
- Industry's only UL Listed and CSA Certified fuse with a 300kA interrupting rating that allows for simple, worry-free installation in virtually any
- 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 coordination 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. Can often be sized for back-up protection against motor burnout from
overload or singlephasing if other overload protective devices fail.
- Proper sizing can provide "no damage" Type 2 coordinated protection for NEMA and IEC motor controllers.
- Space-saving package for equipment downsizing.
