Why Choose the Mersen ATQ2-1/4 Time-Delay Fuse?
The Mersen ATQ2-1/4 is a reliable 2.25 A time-delay midget fuse designed to provide supplementary overcurrent protection for industrial control circuits and electrical equipment. As part of the trusted Mersen Amp-Trap® ATQ series, it is ideal for applications where temporary inrush currents occur during normal equipment start-up, such as transformers, relays, solenoids and lighting circuits.
Its time-delay characteristic allows the fuse to withstand brief start-up current surges without nuisance operation while providing dependable protection against sustained overloads and short-circuit faults. This helps improve equipment reliability and reduce unnecessary downtime in industrial environments.
With a rated current of 2.25 A and a voltage rating of 500 V AC, the ATQ2-1/4 is suitable for industrial machinery, automation systems and commercial electrical equipment. Its standard 10 × 38 mm midget fuse construction allows quick installation into compatible fuse holders and control panels.
