Why Choose the Mersen ATQ25 Time-Delay Fuse?
The Mersen ATQ25 is a dependable 25 A time-delay midget fuse designed to provide supplementary overcurrent protection for industrial control circuits and electrical equipment. Part of the established Mersen Amp-Trap® ATQ series, it is suitable for circuits containing transformers, motors, solenoids and other inductive loads that produce temporary inrush currents during normal start-up.
Its time-delay operating characteristic allows the fuse to tolerate brief current surges without unnecessary operation. During a sustained overload or short-circuit condition, the ATQ25 interrupts the circuit to help protect wiring, control components and connected equipment from electrical damage.
With a rated current of 25 A and a voltage rating of up to 500 V AC, the Mersen ATQ25 is suitable for industrial machinery, automation equipment and commercial electrical installations. Its standard 10 × 38 mm midget format enables straightforward installation in compatible fuse holders and panel-mounted fuse clips.
