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.

Class J Fuses
UL-listed Class J fuses are designed for delivering a high interrupting rating and preventing nuisance blowing caused by motor and equipment startup. These current-limiting fuses eliminate the occurrence of electrical damage by disconnecting the circuits before they are exposed to the full magnitude and duration of overcurrent. Raptor Supplies offer a wide range of these products from brands like Bussmann and Ferraz Shawmut. Class J fuses by Ferraz Shawmut are made of fibreglass providing dimensional stability in harsh industrial environments. The 600VAC fuses are capable of interrupting a maximum of 200000 A current, thereby suitable for installations in capacitors, panelboards, bus ducts and circuit breakers. Bussmann Class J fuses feature dual-element construction providing motor overload, ground fault and short-circuit protection. These time-delay fuses can be sized close to full load amps and hold until the temporary surges and overload occurrence subside without breaking the contacts. They are available in cylindrical and blade type body styles with indicating & non-indicating variants for identifying the status of a blown fuse.
