Why Choose the Mersen ATQ3 Time-Delay Fuse?
The Mersen ATQ3 is a reliable 3 A time-delay midget fuse designed to provide supplementary overcurrent protection for industrial control circuits and electrical equipment. Part of the established Mersen Amp-Trap® ATQ series, it is suitable for circuits containing transformers, relays, solenoids and other inductive loads that produce temporary inrush currents during normal start-up.
Its time-delay operating characteristic allows the fuse to withstand brief current surges without unnecessary operation. During a sustained overload or short-circuit fault, the ATQ3 interrupts the circuit to help protect wiring, control components and connected equipment from electrical damage.
Rated at 3 A and 500 V AC, the Mersen ATQ3 is suitable for industrial machinery, automation equipment and commercial electrical installations. Its standard cylindrical midget format and ferrule terminals enable straightforward clip mounting in compatible fuse holders and control panels.

Reliable Protection for Industrial Control Equipment
The Mersen ATQ3 is engineered to distinguish between harmless temporary start-up surges and sustained overcurrent conditions. This makes it particularly effective in circuits containing inductive components that may briefly draw more than their normal operating current when energised.
Its compact midget construction allows the ATQ3 to be incorporated easily into industrial control cabinets, OEM machinery and automation systems. Correct fuse selection helps protect valuable equipment, improve operational reliability and minimise unnecessary maintenance interruptions.
