Why Choose the Mersen ATQ1-1/8 Time-Delay Midget Fuse?
The Mersen ATQ1-1/8 is a premium time-delay midget fuse designed to provide dependable supplementary overcurrent protection for industrial control circuits, transformers, solenoids, relays and other electrical equipment. As part of the trusted Mersen Amp-Trap® ATQ series, it is engineered to tolerate normal temporary inrush currents while delivering reliable protection against sustained overloads and short circuit conditions.
Its time-delay characteristic helps minimise nuisance fuse operation during transformer energisation, motor starting and equipment start-up, improving system reliability and reducing unnecessary downtime. The compact 10 × 38 mm midget format enables straightforward installation into compatible fuse holders where panel space is limited.
With a rated current of 1.125 A (1-1/8 A), a 500 V AC voltage rating and a 10 kA AC interrupting rating, the Mersen ATQ1-1/8 is ideal for supplementary protection of industrial equipment where available fault current does not exceed 10,000 A. It is intended for supplementary protection only and is not suitable for branch circuit protection.
