Cooper Bussmann BP/NON-40 Type Non Cartridge Fuse 40A 2PK

Product Description

The COOPER BUSSMANN BP/NON-40 is a Type NON one-time cartridge fuse rated at 40 amps and 250 volts, sold in a convenient 2-pack carded format. Designed for general-purpose overcurrent protection, this fuse provides reliable branch circuit and equipment protection in residential, commercial, and light industrial applications. The ferrule-style cartridge body measures 2.75 inches in length and 1.375 inches in width, fitting standard Class K5 fuse holders and disconnect blocks. Electricians and maintenance technicians reach for this fuse type when a straightforward, non-renewable overcurrent device is required for loads that do not demand time-delay characteristics.

The BP/NON-40 is suited for general-purpose electrical systems where branch circuit protection up to 250 volts AC is needed. Typical applications include lighting circuits, motor branch circuits with appropriate sizing, HVAC disconnect boxes, and general load centers. The one-time design means the fuse must be replaced after an overcurrent event rather than reset, making it appropriate for installations where definitive fault indication is preferred. The carded retail packaging simplifies jobsite inventory and point-of-sale handling.

Installation Notes

Installation and replacement of cartridge fuses should be performed by a qualified electrician in accordance with NFPA 70 (National Electrical Code) requirements. Always de-energize and verify absence of voltage on the circuit before opening a fused disconnect or fuse holder. Use an appropriate fuse puller tool to remove and install ferrule cartridge fuses — never handle them on a live circuit. Confirm the replacement fuse amp rating matches the circuit's overcurrent protection requirements before restoring power.
