LITTELFUSE Class J Fuses
LPJ Low-Peak Time Delay Fuses, Dual Element, Class J, With Indictaor
Bussmann LPJ Series Class J fuses are designed to avoid frequent blowing during motor and equipment startups. They feature a compact design for equipment downsizing and optimising space usage. These fuses can handle high interrupting ratings up to 300kA for worry-free installation. They feature low-peak fuses in the series and have consistent 2:1 ampacity ratios for selective coordination of fuses. They have dual elements and offer time-delay characteristics for optimal protection for the connected equipment. These fuses offer current-limiting capabilities to protect downstream components from the thermal and magnetic effects of short-circuit currents. They provide backup protection against motor burnout caused by overload or single-phasing, acting as a secondary protective measure. These dual-element fuses have low resistance for cool operation and improved efficiency.
