Lifesafety Power ATM-3-FUSE-BOXED(BAGOF25) 32V 3A Replacement Fuse (Pack of 25)

Overview

The ATM-3-FUSE-BOXED(BAGOF25) is a 32V, 3A replacement fuse designed for Lifesafety Power backup power supplies and UPS systems. This fuse protects against overcurrent conditions and electrical faults in access control, CCTV, and door strike circuits. The pack of 25 is sized for integrators managing multiple installations or maintaining inventory for emergency replacements.

Compatibility

This fuse is rated for Lifesafety Power ATM series backup power supplies and compatible 32V DC circuit protection applications. Verify your enclosure's fuse specification before installation — using an incorrect amperage rating can result in nuisance trips or inadequate protection. Consult your power supply documentation or contact technical support if you are uncertain whether this fuse matches your system's requirements.

Key Specifications

• Voltage Rating: 32V DC — protects circuits in standard access control and security power distribution systems.
• Current Rating: 3A — sized for typical backup power branch circuits; higher ratings protect larger loads, lower ratings protect branch circuits with higher sensitivity requirements.
• Quantity: Pack of 25 — one replacement fuse or bulk backup inventory for multi-site deployments.

Installation Notes

Before replacement, verify the system is de-energized and the failed fuse is cool. Install the replacement fuse into the same cartridge or holder, ensuring it seats firmly. Do not bypass or upsize the fuse rating; this defeats circuit protection and risks equipment damage or fire hazard. If fuses blow repeatedly, investigate the underlying circuit fault rather than replacing fuses continuously.
