Why Choose the Mersen ATM3 Fast-Acting Fuse?
The Mersen ATM3 is a compact fast-acting midget fuse designed to provide supplementary overcurrent protection for industrial control circuits, instrumentation, power supplies and electrical equipment. As part of the established Mersen Amp-Trap® ATM series, it responds rapidly to overloads and short circuits, helping protect conductors and connected components from damaging fault currents.
Rated at 3 A and up to 600 V AC/DC, the ATM3 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 prolonged tolerance of motor, transformer or capacitor inrush currents.
The ATM3 uses a compact cylindrical ferrule construction in the standard 10 × 38 mm midget fuse format. Its current-limiting design and high interrupting capacity make it a practical choice for control-panel builders, OEM manufacturers, automation engineers and industrial maintenance professionals. ATM-series fuses are intended for supplementary protection and should only be used within their applicable approvals and circuit requirements.

Fast Protection for Sensitive Electrical Circuits
The Mersen ATM3 is engineered to interrupt excessive current rapidly, helping protect electrical equipment before prolonged fault current can generate damaging heat or mechanical stress. This fast response is well suited to circuits containing sensitive components that require prompt isolation during an overload or short circuit.
Its current-limiting construction helps restrict the peak current and energy permitted to pass during a fault. This can reduce equipment damage, support reliable operation and minimise disruption within industrial control and automation systems.
