Why Choose the Mersen ATQ15 Time-Delay Fuse?
The Mersen ATQ15 is a robust 15 A time-delay midget fuse designed to provide dependable supplementary overcurrent protection for industrial control circuits and electrical equipment. Part of the trusted Mersen Amp-Trap® ATQ series, it is engineered for applications where temporary inrush currents are common, including transformers, motors, solenoids and lighting control circuits.
Its time-delay characteristic allows the fuse to withstand short-duration current surges during equipment start-up while still providing reliable protection against sustained overloads and short-circuit faults. This helps minimise nuisance fuse operation while maintaining the safety and reliability of industrial electrical systems.
With a rated current of 15 A and a 500 V AC voltage rating, the ATQ15 is ideal for supplementary protection in commercial and industrial control panels. Its industry-standard 10 × 38 mm midget format enables easy installation in compatible fuse holders.
