Cooper Bussmann GLR-1 Cartridge Fast-acting Fuse 1A 300V

Product Description

The COOPER BUSSMANN GLR-1 is a glass cartridge fast-acting fuse rated at 1 amp and 300 volts with a 10 kA interrupting rating at AC. It measures 2.25 inches in overall length and 0.63 inches in diameter, fitting standard cartridge fuse holders. Fast-acting fuses respond immediately to overcurrent conditions without intentional delay, making them well suited for protecting sensitive components and circuits where quick response is required. The glass body allows visual inspection of the fuse element without removing the fuse from the holder. Licensed electricians and instrumentation technicians are the typical installers of this fuse type.

This fuse is used in residential, commercial, and light industrial electrical applications where a non-rejecting cartridge fuse is specified. Typical installation scenarios include control panels, instrumentation enclosures, and equipment requiring branch-circuit or supplemental overcurrent protection at 300 volts or below. The non-rejecting design allows use in standard open-style fuse holders without a keyed or rejection-style block requirement.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lock out the circuit before removing or installing a fuse. Confirm the fuse holder is rated for the voltage and current of the application before inserting the fuse. Never replace a fuse with a unit rated higher than the circuit requires.
