Mersen ATMR1/2 Class CC Amp-Trap Fast Acting Fuses, 600V AC, 0.500A

Protect sensitive control and security equipment with the Mersen Electrical Power ATMR1/2 Class CC Amp-Trap fast-acting fuse. Designed for branch-circuit and control-circuit protection, this compact 600V AC, 0.500A fuse delivers current-limiting performance that reduces fault energy and helps safeguard transformers, PLCs, and surveillance power supplies. The rejection-style dimensions prevent substitution by lower-rated parts, cutting maintenance errors and minimizing system downtime in critical monitoring and security installations.

As a fast-acting Class CC fuse, the ATMR1/2 is ideal where short-circuit currents can exceed 10,000 amps and where tight coordination with downstream electronics is required. Its small footprint makes it a practical choice for crowded enclosures used in networking closets, security cabinets, and control panels. Whether protecting CCTV power supplies, access control transformers, or industrial control circuits, this Amp-Trap fuse offers reliable, economical protection.
