Why Choose the Mersen ATQ1-4/10 Time-Delay Fuse?
The Mersen ATQ1-4/10 is a compact and dependable 1.4 A time-delay midget fuse designed to provide supplementary overcurrent protection for industrial electrical equipment and control circuits. As part of the established Mersen Amp-Trap® ATQ series, it is suitable for applications where temporary inrush currents occur during normal equipment start-up.
Its time-delay operating characteristic allows the fuse to tolerate brief current surges from transformers, relays, solenoids and other inductive devices without unnecessary operation. During a sustained overload or short-circuit condition, the fuse interrupts the circuit to help protect wiring and connected components from electrical damage.
With a rated current of 1.4 A and a voltage rating of up to 500 V AC, the ATQ1-4/10 is well suited to industrial control panels, machinery and commercial electrical equipment. Its standard 10 × 38 mm midget format enables straightforward installation in compatible fuse holders.

Reliable Protection for Low-Current Equipment
Time-delay fuses such as the Mersen ATQ1-4/10 are designed to distinguish between harmless temporary current surges and sustained overcurrent conditions. This makes them particularly useful in circuits containing inductive components that may draw a higher current for a short period when initially energised.
The compact midget fuse format makes the ATQ1-4/10 easy to incorporate into electrical control cabinets, machinery panels and automation equipment. Correctly selected fuse protection can help reduce equipment damage, improve operational reliability and simplify electrical maintenance.
Typical Applications
- Industrial control panels and machinery.
- Control transformers and power supplies.
- Relays, contactors and solenoid circuits.
- Lighting and heating control equipment.
- Instrumentation and automation systems.
- Commercial and industrial electrical equipment.
