Why Choose the Mersen ATQ2-1/2 Time-Delay Fuse?
The Mersen ATQ2-1/2 is a dependable 2.5 A time-delay midget fuse designed to provide supplementary overcurrent protection for industrial control circuits and electrical equipment. 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 components without unnecessary operation. During a sustained overload or short-circuit condition, the ATQ2-1/2 interrupts the circuit to help protect wiring and connected equipment from electrical damage.
With a rated current of 2.5 A and a voltage rating of up to 500 V AC, the Mersen ATQ2-1/2 is ideal for industrial machinery, automation systems and commercial electrical equipment. Its standard 10 × 38 mm midget format enables straightforward installation in compatible fuse holders and electrical control panels.

Reliable Protection for Industrial Control Equipment
Time-delay fuses such as the Mersen ATQ2-1/2 are designed to distinguish between temporary start-up surges and sustained overcurrent conditions. This makes the fuse particularly effective in circuits containing inductive devices that may briefly draw more than their normal operating current when energised.
The compact midget fuse format allows the ATQ2-1/2 to be incorporated easily into industrial control cabinets, machinery panels and automation systems. Correct fuse selection helps 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.
