Why Choose the Mersen ATQ12 Time-Delay Fuse?
The Mersen ATQ12 is a dependable 12 A time-delay fuse designed to protect electrical equipment and circuits against damaging overcurrents. Manufactured by Mersen, formerly known as Ferraz Shawmut, this compact fuse is suitable for industrial control systems, transformers, solenoids and other applications where temporary current surges may occur during normal operation.
Its time-delay operating characteristic allows the ATQ12 to withstand brief inrush currents without unnecessary fuse operation, while still providing reliable protection during sustained overloads and short-circuit conditions. This makes it particularly useful for inductive equipment that can draw elevated current during start-up.
With a current rating of 12 A and a voltage rating of up to 500 V AC, the Mersen ATQ12 provides compact circuit protection for commercial and industrial electrical installations. Its standard midget-format cylindrical body enables straightforward installation in compatible fuse holders and control panels.
