Eaton GMF-3/10 300V Small Dimension Fuse 0.3 Amp

Product Description

The EATON GMF-3/10 is a 300-volt small-dimension glass tube fuse rated at 0.3 amps (3/10 amp), designed to protect sensitive instruments, controls, and low-voltage circuits from overcurrent faults. This fuse belongs to the Buss GMF series, a widely recognized line of miniature fuses used throughout the HVAC, electrical, and electronics service trades. The GMF-3/10 provides fast-acting overcurrent protection in compact control panels and instrument enclosures where standard-size fuses will not fit. At 0.015 pounds, it is a lightweight, single-use protective device intended for straightforward field replacement by licensed electricians and HVAC controls technicians.

The GMF-3/10 is used in residential and light commercial control circuits, instrument panels, and electronic equipment that require a small-body fuse with a 300-volt rating. Common applications include low-voltage control boards, measuring instruments, signal circuits, and auxiliary control wiring found in HVAC equipment, motor control centers, and industrial control panels. Technicians working on equipment that calls out a GMF-series small-dimension fuse will find this a direct form-factor match.

Key Features

• 300-volt rating supports a broad range of low- and medium-voltage control circuit applications
• 0.3 amp (3/10 amp) current rating provides precise overcurrent protection for sensitive instrument circuits
• Small-dimension glass tube body fits compact fuse holders and instrument panels
• Fast-acting response helps protect downstream electronics and control components
• Lightweight at 0.015 pounds — easy to carry multiples in a service kit

Compatibility

Designed as an OEM-style replacement for small-dimension instrument fuse holders accepting GMF-series fuses rated at 300 volts and 3/10 amp.

Installation Notes

Installation of this fuse should be performed by a qualified electrician or licensed HVAC controls technician. Always de-energize and lock out the circuit before removing or installing a fuse, in accordance with NFPA 70E electrical safety procedures. Verify the replacement fuse matches the ampere and voltage ratings marked on the equipment nameplate or wiring diagram before installation. Never substitute a higher-rated fuse to bypass a recurring overcurrent condition — diagnose the root cause of the fault first.
