Cooper Bussmann BP/NON-45 Cartridge Fuse 45A 250V 2 Pack

Product Description

The COOPER BUSSMANN BP/NON-45 is a Type NON one-time cartridge fuse rated at 45 amps and 250 volts, sold in a 2-pack carded format. It provides general-purpose overcurrent protection in branch circuits, feeder circuits, and equipment where non-renewable fuse protection is required. The ferrule-style cartridge body measures 2.75 inches long by 1.375 inches wide by 0.50 inches high. Electricians and maintenance technicians use this fuse as a straightforward, cost-effective means of protecting circuits in compliance with applicable electrical codes. Each pack contains two individual fuses for common replacement needs.

This fuse is suited for residential, light commercial, and industrial applications where a 250-volt, 45-amp general-purpose fuse is specified. Typical installation locations include panelboards, disconnect switches, fuse blocks, and equipment control panels. The Type NON designation indicates a non-time-delay fuse, meaning it responds quickly to overcurrent conditions without an intentional delay. This makes it appropriate for circuits without high inrush loads such as resistive heating elements, lighting circuits, and general wiring protection.

Key Features

• 45-amp current rating with 250-volt AC maximum voltage rating
• Type NON non-time-delay design for fast response to overcurrent faults

• One-time fuse construction — replace after operation, not resettable
• Carded 2-pack format keeps replacement fuses organized for service calls
• General-purpose rating suitable for resistive and low-inrush circuit protection

Compatibility

Designed as an OEM-style replacement for standard ferrule cartridge fuse holders and disconnect switches accepting Type NON cartridge fuses at 45 amps and 250 volts.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NFPA 70 (National Electrical Code) requirements. Always de-energize and lock out the circuit or disconnect before removing or installing a fuse. Use an appropriate fuse puller tool when removing cartridge fuses from live or recently energized fuse clips to avoid arc flash exposure. Verify the replacement fuse amperage and voltage rating match the circuit requirements before installing.
