Why Choose the Mersen ATM25 Fast-Acting Fuse?
The Mersen ATM25 is a compact fast-acting midget fuse designed to provide supplementary overcurrent protection for industrial control circuits, instrumentation, power supplies and electrical equipment. Part of the established Mersen Amp-Trap® ATM series, it interrupts overloads and short circuits rapidly to help limit damage to conductors and connected components.
Rated at 25 A and 600 V AC/DC, the ATM25 is suitable for demanding industrial and commercial electrical systems. Its fast-acting operating characteristic makes it particularly appropriate for circuits requiring prompt fault clearance rather than extended tolerance of motor, transformer or capacitor inrush currents.
The ATM25 uses a cylindrical ferrule construction measuring approximately 10.4 × 38.1 mm. Its compact midget format, current-limiting performance and 100 kA AC interrupting rating make it a practical choice for panel builders, OEM manufacturers, automation engineers and industrial maintenance professionals. The ATM25 is intended for supplementary protection and is not approved for branch-circuit protection.

Fast Protection for Industrial Electrical Circuits
The Mersen ATM25 is engineered to interrupt excessive current rapidly, helping protect electrical equipment before prolonged fault current can generate damaging levels of heat or mechanical stress. This fast response is well suited to non-inductive circuits and other applications where immediate fault clearance is required.
Its current-limiting construction helps restrict the peak current and energy permitted to pass during a short circuit. This can reduce equipment damage, improve system reliability and support safer maintenance of industrial control and power-distribution equipment.
Typical Applications
- Industrial control panels and auxiliary circuits.
- Instrumentation and measurement equipment.
- Power supplies and electronic control equipment.
- Automation systems and OEM machinery.
- Lighting and heating control circuits.
- Commercial and industrial electrical equipment.

Frequently Asked Questions
What is the Mersen ATM25 used for?
The ATM25 provides supplementary overcurrent and short-circuit protection for industrial control circuits, instrumentation, power supplies and compatible electrical equipment.
What is the current rating of the ATM25?
The Mersen ATM25 has a rated current of 25 A.
What voltage is the ATM25 rated for?
The ATM25 is rated for applications up to 600 V AC and 600 V DC.
Is the Mersen ATM25 a time-delay fuse?
No. The ATM25 is a fast-acting fuse designed to clear excessive current rapidly rather than tolerate extended inrush currents.
Can the ATM25 be used for branch-circuit protection?
No. Mersen specifies that ATM-series midget fuses are intended for supplementary protection and must not be used as branch-circuit protection devices.
What fuse holder should be used with the ATM25?
The ATM25 should be installed in a compatible midget fuse holder or fuse block rated for the circuit voltage, current and required interrupting capacity.
