Cooper Bussmann LPJ-5-6/10SP Class J Fuse 5.6A

Product Description

The COOPER BUSSMANN LPJ-5-6/10SP is a Class J time delay cartridge fuse rated at 5.6 amps. It is designed for general-purpose overcurrent protection in industrial and commercial electrical systems. The dual-element, time delay construction allows it to tolerate temporary inrush currents without nuisance tripping, while still providing fast response to sustained fault conditions. With an interrupting rating of 100 kA at DC and 300 kA at AC (RMS), this fuse handles high fault-current environments safely. It mounts in a standard Class J fuse holder. Licensed electricians and industrial maintenance technicians are the primary installers.

This fuse is suited for motor branch circuits, control panels, and equipment protection applications where Class J current-limiting performance is required. Its time delay characteristic makes it appropriate for loads with high inrush currents, such as motors and transformers. The non-indicating body provides no visual blown indication, so fuse testing equipment should be used during troubleshooting. It is sold individually but must be ordered in multiples of 3.

Installation Notes

Installation must be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. Always de-energize and lock out the circuit before removing or installing fuses. Use a properly rated fuse puller for cartridge fuse removal. Verify the replacement fuse class, amperage, and voltage rating match the circuit requirements before energizing.
