Mersen AG25 480V Class G Fuse 4 Pack

Product Description

The MERSEN AG25 is a 480-volt Class G fuse designed for branch-circuit and control-circuit overcurrent protection in commercial and industrial electrical systems. Class G fuses are compact, non-interchangeable rejection-style fuses that provide reliable short-circuit protection where space is limited. Sold in a pack of four, the AG25 is a go-to replacement for electrical contractors and maintenance technicians working on motor control centers, control panels, and similar low-voltage distribution equipment. The small form factor, measuring approximately 1.66 inches by 0.44 inches by 1.69 inches, makes it well suited for tight enclosures and control cabinets.

The AG25 is used in residential, commercial, and light industrial applications wherever a 480-volt Class G fuse holder is present. Typical installations include motor starters, control transformers, and branch-circuit panelboards requiring a rejection-style fuse to prevent accidental substitution with a lower-rated fuse. Electricians servicing existing control panels or performing new installations will find this a direct-fit replacement for standard Class G fuseholders rated at 480 volts.

Compatibility

Designed as an OEM-style replacement for standard 480-volt Class G fuseholders in commercial and industrial control panels and motor control equipment.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements for overcurrent protection devices. Always de-energize and lock out the circuit before replacing any fuse. Verify the fuseholder is rated for Class G fuses and confirm the voltage and ampere rating match the circuit requirements before installing. Do not exceed the fuseholder's rated voltage or current capacity.
