Eaton NON-10 Cartridge Fuse 10A 250V Class K5

Product Description

The EATON NON-10 is a one-time, general-purpose cartridge fuse rated at 10 amps and 250 volts. It provides overcurrent protection in non-current-limiting applications where fast, no-time-delay response is required. Built to UL Class K5 standards with an interrupting rating of 50,000 AIC, this fuse uses ferrule-end construction for secure contact in standard fuse holders. Licensed electricians and maintenance technicians install this type of fuse in lighting circuits, main panel protection, and branch circuits that do not include large electric motors or significant inductive loads.

The NON-10 is suited for residential and light commercial electrical systems where straightforward overcurrent protection is needed. Typical applications include lighting branch circuits, small appliance circuits, and general-purpose panel protection. It is not intended for circuits with heavy motor loads, as those applications typically require time-delay fuses to handle inrush current without nuisance opening.

Key Features

• 10-amp rating with 250-volt maximum voltage
• No time delay — fast-acting response for lighting and non-motor circuits
• UL Listed Class K5 with 50,000 AIC interrupting rating
• Ferrule-end construction for standard cartridge fuse holders
• One-time fuse — must be replaced after operation

Compatibility

Designed as a general-purpose replacement cartridge fuse for use in standard ferrule-type fuse holders rated for Class K5 fuses up to 250 volts.

Installation Notes

Installation and replacement must be performed by a qualified electrician in accordance with the National Electrical Code (NEC). Always de-energize and lock out the circuit before removing or installing a fuse. Use an appropriate fuse puller for ferrule-end cartridge fuses — never handle a fuse in an energized holder. Verify the replacement fuse rating matches the circuit overcurrent protection requirements before restoring power.
