Cooper Bussmann LPJ-2SP Class J Time Delay Fuse 2A

Product Description

The COOPER BUSSMANN LPJ-2SP is a Class J time delay cartridge fuse rated at 2 amps. It is designed for general purpose overcurrent protection in industrial control panels, motor branch circuits, and commercial electrical systems. The dual-element, time delay design allows the fuse to tolerate brief inrush currents without nuisance tripping while still providing fast response to sustained overloads and short circuits. With an interrupting rating of 100 kA at DC and 300 kA at AC (RMS), this fuse is suited for high fault-current environments. The cartridge body measures 20.6 mm in diameter and 57.20 mm in length, mounting in a standard Class J fuse holder.

This fuse is used in residential, commercial, and light industrial applications where Class J fusing is specified. Typical installations include motor control centers, disconnect switches, panelboards, and equipment requiring UL Listed Class J overcurrent protection. It is installed by licensed electricians during new installation or service work on control circuits and branch circuit protection systems. The non-indicating body provides no visual blown indicator, so continuity testing is required during troubleshooting.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lockout/tagout the circuit before replacing or installing this fuse. Verify that the fuse holder is rated for Class J fuses and that the replacement fuse amperage matches the circuit requirements. Do not install a fuse with a higher amperage rating than specified by the equipment manufacturer or circuit design.
