Mersen ATQ30 Amp-Trap Midget Time Delay Fuses, 500V AC, 30A

Protect critical security, surveillance and monitoring circuits with the Mersen Electrical Power ATQ30 Amp-Trap midget time-delay fuse. This compact fuse delivers dependable supplemental protection for control panels, camera power supplies and access-control equipment where preventing nuisance openings and preserving uptime are priorities. The ATQ30 is rated 30A at 500VAC and incorporates a time-delay characteristic (12 seconds at 200% of rating) to ride through equipment inrush currents without sacrificing fast-acting fault protection.

Designed for supplemental circuit protection (not for branch-circuit protection), the ATQ series is ideal when available short-circuit current does not exceed 10,000A. Its 10 mm x 38 mm midget footprint fits standard UltraSafe fuse holders for safe, convenient replacement and system integration. Choosing the Mersen ATQ30 means fewer service calls, better coordination with downstream devices, and reliable protection for low-voltage security and monitoring applications. Order the ATQ30 to safeguard your next security or surveillance installation or contact our sales team to confirm fit and coordination for your system.
