Why Choose the Mersen ATQ30 Time-Delay Fuse?
The Mersen ATQ30 is a dependable 30 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 well suited to circuits containing transformers, motors, solenoids and other inductive loads that generate temporary inrush currents during normal start-up.
Its time-delay operating characteristic enables the fuse to tolerate brief current surges without unnecessary operation. When a sustained overload or short-circuit fault occurs, the ATQ30 interrupts the circuit to help protect conductors, control components and connected equipment from electrical damage.
Rated at 30 A and 500 V AC, the Mersen ATQ30 is suitable for industrial machinery, automation equipment and commercial electrical installations. Its standard 10 × 38 mm midget format allows straightforward installation in compatible fuse holders and panel-mounted fuse clips.

Reliable Protection for Industrial Electrical Equipment
The Mersen ATQ30 is engineered to distinguish between harmless temporary start-up surges and sustained overcurrent conditions. This makes it particularly suitable for circuits containing inductive equipment that may briefly draw substantially more than its normal operating current when energised.
Its compact cylindrical construction allows the ATQ30 to be incorporated easily into industrial control panels, OEM machinery and automation systems. Correct fuse selection helps protect valuable equipment, improve operating reliability and minimise unnecessary maintenance interruptions.
Typical Applications
- Industrial control panels and machinery.
- Motor control and auxiliary circuits.
- Control transformers and power supplies.
- Solenoid and contactor circuits.
- Lighting and heating control equipment.
- Automation systems and OEM equipment.
