Eaton BP/NON-100 Cartridge Fuse 100A 250V Class K5

Product Description

The EATON BP/NON-100 is a 100-amp, 250-volt general-purpose one-time cartridge fuse designed for non-current-limiting applications. Rated Class K5 with a 50,000 ampere interrupting rating (AIR), it carries a UL listing and features ferrule ends for secure cartridge-style installation. This fuse provides no time delay, meaning it opens immediately on an overcurrent condition. Licensed electricians and maintenance technicians install this fuse in branch circuits, lighting panels, and main panel protection applications where large electric motors are not part of the load.

The BP/NON-100 is suited for residential and light commercial electrical systems. Typical applications include non-current-limiting lighting circuits and main distribution panel protection. It is not intended for circuits with large motor loads, where inrush current at startup would cause nuisance opening. The one-time construction means the fuse must be replaced after a single overcurrent event.

Key Features

• 100-amp continuous current rating at 250 volts
• Class K5 rating with 50,000 AIR for solid fault protection
• UL listed for recognized safety compliance
• Ferrule ends for standard cartridge fuse holder fitment
• No time delay — immediate response to overcurrent conditions
• One-time fuse — replace after each operation

Compatibility

Designed as an OEM-style replacement for standard cartridge fuse holders accepting ferrule-end fuses rated at 250 volts in non-current-limiting lighting and panel protection circuits.

Installation Notes

Installation and replacement of cartridge fuses should be performed by a licensed electrician following NEC requirements. Always de-energize and lock out the circuit before removing or inserting a fuse. Use an insulated fuse puller rated for the voltage of the circuit — never remove a cartridge fuse by hand while the circuit is live. Verify the replacement fuse rating matches the circuit overcurrent protection requirements before restoring power.
