Ferraz Shawmut ATMR25 Cc Fast-acting Fuse 25A

Product Description

The FERRAZ SHAWMUT ATMR25 is a CC-class fast-acting cylindrical fuse rated at 25 amps. Designed for electrical circuit protection, it responds rapidly to overload and short-circuit conditions, interrupting fault current before downstream components are damaged. The ATMR25 features a fiberglass and GMG body construction with a 10.3 mm diameter form factor. It carries an interrupting rating of 100 kA at DC and 200 kA at AC, making it suitable for demanding industrial and commercial panel applications. Licensed electricians install this fuse as part of branch-circuit and control-circuit protection in panels, fusible disconnects, and fuse blocks.

The ATMR25 is used in residential, commercial, and light industrial electrical installations wherever CC-class fuse protection is required. Its fast-acting response makes it appropriate for protecting sensitive electronic equipment, motor control circuits, and power distribution panels against sustained overloads and short circuits. The compact 10.3 mm diameter body fits standard CC-class fuse holders and blocks.

Installation Notes

Installation should be performed by a qualified electrician in accordance with applicable NEC requirements. Always de-energize and lock out the circuit before replacing fuses. Use an appropriately rated fuse puller when removing or inserting cylindrical fuses to avoid contact with live terminals. Verify that the replacement fuse matches the required ampere rating and interrupt rating for the circuit before restoring power.
