Mersen ATQ1/2 Amp-Trap Midget Time Delay Fuses, 500V AC, 1/2A

Protect critical security and monitoring equipment with the Mersen ATQ 1/2 Amp‑Trap midget time‑delay fuse. Designed for surveillance, access control and networking installations, this compact fuse provides dependable, time‑delay protection that withstands inrush currents (12 seconds at 200% rating) so cameras, NVRs and access controllers power up reliably without nuisance interruptions. Rated for 500V AC and 1/2A, the ATQ series offers supplemental protection for circuits where short-circuit current availability does not exceed 10,000A, helping prevent costly equipment failures and service calls.

From rack-mounted network gear to distributed CCTV deployments, the midget form factor (10 mm x 38 mm) makes it easy to retrofit into existing fuse holders or pair with UltraSafe holders for enhanced safety. Backed by Mersen Electrical Power engineering, this Amp‑Trap fuse balances fast response for faults with the time-delay needed for high-inrush industrial and security systems. Specify the ATQ 1/2A fuse to reduce downtime, simplify maintenance, and protect your security, surveillance and monitoring infrastructure.
