Cooper Bussmann GMA-100-R Cartridge Fast-acting Fuse 0.1A

Product Description

The COOPER BUSSMANN GMA-100-R is a miniature glass cartridge fuse rated at 0.1 amps with fast-acting response. It measures 20 mm in overall length and 5 mm in diameter, conforming to the standard IEC 5x20 mm form factor widely used in control panels, instrumentation, and low-voltage electronic equipment. The fast-acting design responds immediately to overloads, providing reliable short-circuit protection without intentional time delay. The glass body allows visual inspection of the element without specialized tools. Electricians and electronics technicians install this fuse in fuse holders and fuse blocks where precise low-amperage overcurrent protection is required.

This fuse is suited for residential and commercial control circuits, industrial instrumentation, HVAC equipment control boards, and consumer electronics requiring miniature overcurrent protection at low amperage. Its 10,000-amp interrupting rating at 125 volts makes it appropriate for branch-circuit and supplemental protection applications where high fault-current capacity is needed relative to the fuse size. The 5x20 mm cartridge format is one of the most common international fuse standards, making this part a straightforward replacement in a wide range of equipment.

Key Features

Compatibility

Designed as a standard IEC 5x20 mm fast-acting miniature cartridge fuse for use in panel-mount and inline fuse holders accepting the 5x20 mm form factor. Consult equipment documentation to confirm amperage and interrupting rating requirements before installation.

Installation Notes

Installation should be performed by a qualified electrician or electronics technician. De-energize and lock out the circuit before removing or inserting fuses. Verify that the replacement fuse amperage, voltage rating, and interrupting rating match the equipment manufacturer specifications exactly — never substitute a higher-amperage fuse. Applicable work must comply with NEC Article 240 and any equipment-specific codes.
