Mersen ATQ3 Amp-Trap Midget Time Delay Fuses, 500V AC, 30A

Protect critical security, surveillance and IT equipment with the Mersen Electrical Power ATQ3 Amp-Trap midget time-delay fuse. Engineered for supplemental protection, this 30A, 500VAC time-delay fuse absorbs temporary inrush currents—rated to withstand 200% of its ampacity for up to 12 seconds—so cameras, PoE switches, and DVR/NVR power supplies start cleanly without unnecessary fuse replacement. The compact 10 mm x 38 mm midget form factor fits common ULTRA SAFE fuse holders and dense enclosure layouts, making it ideal for rack-mounted networking and low-voltage control panels. With proven interruption performance for systems with available short-circuit current up to 10,000A, the ATQ3 delivers reliable protection where space, repeatability and uptime matter. Note: intended for supplemental protection of equipment (not for branch circuit protection). Specify Mersen ATQ series fuses when you need durable, time-delay protection across surveillance, monitoring, access control and other physical security applications. Order the ATQ3 to safeguard your power rails and reduce service calls.
