Why Choose the Mersen ATQ1/10 Time-Delay Midget Fuse?
The Mersen ATQ1/10 is a compact time-delay midget fuse designed to provide dependable supplementary overcurrent protection for sensitive control circuits, transformers, relays and industrial electrical equipment. As part of the established Mersen Amp-Trap® ATQ series, it tolerates normal short-duration current surges while responding effectively to sustained overloads and short circuit conditions.
Its time-delay operating characteristic helps reduce unnecessary fuse operation during transformer energisation and other temporary inrush-current events. This makes the ATQ1/10 a practical choice for low-current industrial applications where a fast-acting fuse could open during normal equipment start-up.
With a rated current of 1/10 A (0.1 A) and a voltage rating of up to 500 V AC, the Mersen ATQ1/10 delivers compact protection for instrumentation, monitoring equipment and sensitive control circuits.
Key Advantages
- Time-delay operation accommodates normal temporary inrush currents.
- 0.1 A current rating for sensitive, low-current electrical circuits.
- Rated for applications operating at up to 500 V AC.
- Helps reduce nuisance fuse operation during equipment energisation.
- Compact midget format conserves space inside electrical enclosures.
- Suitable for instrumentation, transformers, relays and industrial controls.

- Suitable for supplementary overcurrent protection.
Reliable Time-Delay Protection for Sensitive Circuits
Transformers, relays and other inductive components can draw a temporary surge of current when first energised. The time-delay characteristic of the Mersen ATQ1/10 allows normal short-duration surges to pass without unnecessarily opening the circuit, while still providing protection against sustained excessive current.
This operating behaviour helps improve equipment availability and reduces maintenance associated with nuisance fuse replacement. The ATQ1/10 is particularly suitable for applications requiring a compact 0.1 A fuse that combines inrush tolerance with dependable supplementary protection.
Typical Applications
- Industrial control panels.
- Instrumentation and monitoring equipment.
- Control transformers.
- Relay and contactor circuits.
- Alarm and signalling circuits.
- Electronic control equipment.
- OEM machinery and electrical assemblies.
- Supplementary circuit protection.
