LPJ-400SP Industrial & Electrical Fuses 600V 400A Dual Element Time Delay

LPJ-400SP Industrial & Electrical Fuses 600V 400A Dual Element Time Delay. Bussmann® series Ultimate protection LPJ Class J dual element, current-limiting, time-delay fuses available with optional open fuse indication. 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 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 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 single-phasing 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.
