Why Choose the Mersen ATQ1/2 Time-Delay Midget Fuse?
The Mersen ATQ1/2 is a high-quality time-delay midget fuse designed to provide dependable supplementary overcurrent protection for industrial control circuits, transformers, solenoids and other low-current electrical equipment. As part of the trusted Mersen Amp-Trap® ATQ series, it is engineered to withstand normal inrush currents while responding reliably to sustained overloads and short circuit conditions.
Its time-delay characteristic helps minimise nuisance fuse operation during transformer energisation, motor starting and other temporary current surges. The compact 10 × 38 mm midget format allows simple installation into compatible fuse holders where space is limited.
With a rated current of 1/2 A (0.5 A), a 500 V AC voltage rating and an interrupting capacity of 10 kA, the Mersen ATQ1/2 is an excellent choice for supplementary protection of industrial electrical equipment where available short-circuit current does not exceed 10,000 A. It is not intended for branch circuit protection.
