Why Choose the Mersen ATQ1/8 Time-Delay Midget Fuse?
The Mersen ATQ1/8 is a premium time-delay midget fuse engineered to provide dependable supplementary overcurrent protection for industrial control circuits, transformers, solenoids, relays and other low-current electrical equipment. As part of the trusted Mersen Amp-Trap® ATQ series, it withstands normal temporary inrush currents while responding reliably to sustained overloads and short circuit conditions.
Its time-delay operating characteristic helps minimise nuisance fuse operation during transformer energisation and equipment start-up, making it an ideal solution where temporary current surges are expected. The compact 10 × 38 mm midget format allows straightforward installation into compatible fuse holders while conserving valuable panel space.
With a rated current of 1/8 A (0.125 A), a 500 V AC voltage rating and a 10 kA interrupting rating, the Mersen ATQ1/8 is designed for supplementary protection of industrial circuits where the available fault current does not exceed 10,000 A. It is not intended for branch circuit protection.
