The LPJ-15SP is a Low-Peak™ LPJ-series 15A 600VAC/300VDC ultimate protection class-J current-limiting Time-delay Fuse with non-indicating. Reduces existing fuse inventory by up to 33% when upgrading to Low-Peak fuses. Consistent 2:1 ampacity ratios 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 backup 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.
