Why Choose the Mersen ATM4 Fast-Acting Fuse?
The Mersen ATM4 is a compact and dependable fast-acting cylindrical fuse designed to protect electrical control circuits, instrumentation and industrial equipment against short circuits and damaging overcurrents. As part of the established Mersen Amp-Trap ATM fuse series, it provides reliable circuit protection in applications where rapid fault interruption and a space-saving format are required.
This fuse combines a high voltage rating with fast operating characteristics, helping to minimise damage to sensitive components when a fault occurs. Its current-limiting design restricts the amount of energy allowed to pass through the circuit, reducing thermal and mechanical stress on connected equipment.
With a rated current of 4 A and a maximum voltage rating of 600 V AC, the ATM4 is suitable for industrial control panels, test equipment, transformers and branch circuits. Its standard 10 × 38 mm midget fuse format allows straightforward installation in compatible fuse holders and disconnect systems.
