Why Choose the Mersen FR14AM50V1P Cylindrical Fuse-Link?
The Mersen FR14AM50V1P is a reliable 14 × 51 mm aM cylindrical fuse-link with striker designed to provide short-circuit protection for industrial motor circuits and associated switchgear. Manufactured for IEC low-voltage applications, it is suitable for motor starters, control panels and machinery requiring dependable protection against severe fault currents.
As part of the established Mersen FR14 aM ferrule fuse-link range, this model features a durable ceramic body with silver-plated copper contacts for consistent electrical performance and long operational life. Its aM partial-range characteristic allows normal motor starting currents to pass while rapidly interrupting unacceptable short-circuit currents that could damage motors, contactors and installation equipment.
With a rated current of 1 A, an IEC rated voltage of 500 V AC and a high 120 kA breaking capacity, the FR14AM50V1P is suitable for low-current motor control and inductive-load protection applications. Its integrated striker can operate a compatible auxiliary contact, supporting remote fault indication, alarm signalling and control functions.

Reliable Protection for Industrial Motor Circuits
The Mersen FR14AM50V1P is designed to protect motor circuits, transformers and other inductive loads against damaging short-circuit currents. Its aM characteristic tolerates temporary inrush currents while providing high current limitation and low thermal let-through during severe electrical faults.
Because an aM fuse-link provides partial-range protection, it should normally be coordinated with a suitable overload relay or another protective device. The integrated striker can operate a compatible auxiliary contact when the fuse blows, enabling remote indication, alarms or automatic equipment shutdown.
Typical Applications
- Low-current industrial motor starters.
- Motor control and protection assemblies.
- Transformers and inductive loads.
- Electrical control panels.
- Machine building and OEM equipment.
- Industrial automation and switchgear systems.
