Why Choose the Mersen ATQ10 Time-Delay Midget Fuse?
The Mersen ATQ10 is a dependable time-delay midget fuse designed to provide supplementary overcurrent protection for industrial control circuits, transformers, solenoids, lighting circuits and electrical equipment. As part of the established Mersen Amp-Trap® ATQ series, it tolerates normal temporary current surges while responding effectively to sustained overloads and short circuit conditions.
Its time-delay operating characteristic helps minimise nuisance fuse operation during transformer energisation, motor starting and other brief inrush-current events. The compact cylindrical construction also makes the ATQ10 suitable for control panels and machinery where installation space is limited.
With a rated current of 10 A, a voltage rating of up to 500 V AC and a 10 kA AC interrupting rating, the Mersen ATQ10 provides reliable supplementary protection for industrial equipment. It is intended for supplementary applications and is not a branch circuit fuse.

Reliable Time-Delay Protection for Industrial Equipment
Transformers, solenoids, motors and other inductive loads can draw a temporary surge of current when first energised. The time-delay characteristic of the Mersen ATQ10 allows normal short-duration inrush currents to pass without unnecessarily opening the circuit, while still protecting equipment against sustained excessive current.
This operating behaviour can improve equipment availability and reduce maintenance associated with nuisance fuse replacement. The ATQ10 is particularly suitable for applications requiring a compact 10 A fuse that combines inrush tolerance with dependable supplementary overcurrent protection.
