Why Choose the Mersen ATQ1-1/2 Time-Delay Midget Fuse?
The Mersen ATQ1-1/2 is a premium time-delay midget fuse engineered 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 tolerates 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, motor starting and equipment start-up, making it an ideal choice where temporary current surges are expected. The compact 10 × 38 mm midget design enables straightforward installation into compatible fuse holders while conserving valuable panel space.
With a rated current of 1.5 A, a 500 V AC voltage rating and a 10 kA AC interrupting rating, the Mersen ATQ1-1/2 provides reliable supplementary protection for industrial circuits where the available fault current does not exceed 10,000 A. It is intended for supplementary protection and is not suitable for branch circuit protection.
