Cooper Bussmann GMF-2-8/10 Cartridge Time Delay Fuse

Product Description

The COOPER BUSSMANN GMF-2-8/10 is a glass cartridge time delay fuse rated at 2.8 amps and 300 volts with a 10 kA interrupting rating at AC. Measuring 2.25 inches in overall length and 15.9 mm in diameter, this fuse is designed for installation in a compatible fuse holder. The time delay characteristic allows brief inrush currents to pass without nuisance opening, making it appropriate for use in circuits where motors, transformers, or other inductive loads require startup surge tolerance. Electricians and instrumentation technicians are the primary installers of this component.

This fuse is suited for low-voltage control circuits, instrumentation panels, and light commercial or residential electrical equipment where a compact glass cartridge form factor is required. Its non-rejecting design means it fits standard cartridge fuse holders without keyway restrictions. Applications include HVAC control boards, small motor circuits, and panel-mounted protective circuits operating at or below 300 volts AC. The 2.8 A rating makes it a precise fit for circuits requiring tight overcurrent protection at low amperages.

Installation Notes

Installation must be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before removing or inserting any fuse. Verify the fuse holder is rated for the voltage and current of the application before installation. Do not substitute a fuse of a different amperage or interrupt rating for the one specified in the equipment documentation.
