Why Choose the Mersen ATQ5 Time-Delay Fuse?
The Mersen ATQ5 is a compact and dependable time-delay midget cartridge fuse designed to provide supplemental overcurrent protection for industrial control circuits and electrical equipment. Part of the established Mersen ATQ series, it accommodates temporary inrush currents while protecting connected equipment against sustained overloads and short-circuit conditions.
Rated at 5 A and up to 500 V AC, the ATQ5 is well suited to control transformers, solenoids, relays, lighting circuits and other inductive loads. Its time-delay operating characteristic helps prevent unnecessary fuse operation when equipment is energised, while maintaining reliable circuit protection when a genuine electrical fault occurs.
The fuse features a standard 10 × 38 mm midget cartridge format with ferrule terminals, enabling straightforward installation in compatible fuse holders, fuse blocks and disconnect devices. Its compact size and proven construction make it a practical replacement fuse for industrial machinery, automation panels and commercial electrical systems.

Reliable Protection for Circuits with Inrush Current
Time-delay fuses are designed to tolerate brief current increases associated with the energisation of transformers, solenoids, relays and other inductive equipment. This allows compatible devices to start normally without sacrificing protection against prolonged overloads or damaging fault currents.
The Mersen ATQ5 combines this time-delay performance with a compact midget cartridge format. It can be installed in a correctly rated 10 × 38 mm fuse holder, helping panel builders and maintenance engineers achieve reliable protection without occupying excessive control-panel space.
