Cooper Bussmann LPJ-200SP Class J Time Delay Fuse 200A

Product Description

The COOPER BUSSMANN LPJ-200SP is a Class J time delay cartridge fuse rated at 200 amps, designed for general-purpose overcurrent protection in demanding electrical distribution systems. With an overall length of 5.75 inches and a dual-element construction, it delivers reliable time delay performance that allows motors and other inductive loads to start without nuisance tripping while still providing fast response to sustained fault conditions. The bolt-on mount type ensures a secure, low-resistance connection in fuse blocks and disconnect switches. Installation is performed by qualified electricians working on industrial and commercial power distribution equipment.

This fuse is suited for use in industrial control panels, motor branch circuits, and commercial electrical distribution applications where Class J fuse holders are specified. The dual-element design makes it appropriate for protecting motor loads, transformers, and capacitor banks in both new installations and service replacements. Its interrupt ratings of 100 kA at DC and 300 kA at AC (RMS) make it appropriate for high-fault-current environments common in commercial and light industrial facilities.

Key Features

• 200A continuous current rating with time delay characteristic for motor-circuit compatibility
• Dual-element construction prevents nuisance tripping on inrush currents
• 100 kA interrupt rating at DC and 300 kA interrupt rating at AC (RMS)
• Bolt-on mount type for secure, vibration-resistant termination
• Non-indicating design in a compact 5.75-inch cartridge body
• CE Certified, CSA Certified, RoHS Compliant, and UL Listed (Guide JDDZ File E4273)

Compatibility

Designed for use in Class J fuse holders and disconnect switches rated for 200A cartridge fuses with a 5.75-inch overall length and bolt-on termination.

Installation Notes

Installation and replacement must be performed by a licensed electrician in accordance with NEC Article 240 and applicable local codes. Always de-energize and verify absence of voltage using a properly rated meter before removing or installing fuses. Use insulated fuse pullers or appropriately rated tools for handling cartridge fuses. Never substitute a fuse of a different class, ampere rating, or interrupt rating than what is specified for the circuit.
