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.
Key Advantages
- Industrial-grade 14 × 51 mm IEC cylindrical fuse-link.
- aM motor protection characteristic for short-circuit protection.
- 1 A rated current for low-current motor and inductive-load circuits.
- 500 V AC rated voltage for industrial installations.
- Integrated striker for auxiliary signalling and monitoring.
- 120 kA breaking capacity for reliable fault interruption.
Key Features
- Mersen FR14 aM ferrule fuse-link series.
- 1 A rated current.
- 500 V AC IEC rated voltage.
- 14 × 51 mm cylindrical format.
- aM partial-range protection characteristic.
- Integrated striker for auxiliary contact activation.
- Ceramic insulating body.
- Silver-plated copper ferrule contacts.
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.
