Why Choose the Mersen FR10AM40V20P Cylindrical Fuse-Link?

The Mersen FR10AM40V20P is a reliable 10 × 38 mm aM cylindrical fuse-link with striker designed to provide effective short-circuit protection for industrial motor circuits. Manufactured by Mersen for low-voltage IEC applications, it is suitable for motor starters, control panels and machinery requiring dependable protection against high fault currents.

As part of the established Mersen FR10 aM fuse-link range, this model combines a durable ceramic body with silver-plated copper contacts for reliable electrical performance and long service life. Its aM operating characteristic allows normal motor starting currents to pass while interrupting dangerous short-circuit currents that could damage motors, contactors and associated equipment.

With a rated current of 20 A, an IEC rated voltage of 380 V AC and a high 100 kA breaking capacity, the FR10AM40V20P is suitable for demanding industrial motor protection applications. The integrated striker can activate a compatible auxiliary contact or signalling mechanism when the fuse operates.

Key Advantages

  • Compact 10 × 38 mm cylindrical fuse-link for industrial installations.
  • aM motor protection characteristic designed for short-circuit protection.
  • 20 A rated current for motor and machinery circuits.
  • 380 V AC IEC rated voltage.
  • Integrated striker indication system for auxiliary signalling.
  • 100 kA breaking capacity for dependable fault interruption.

Key Features

  • Mersen FR10 aM cylindrical fuse-link series.
  • 20 A rated current.
  • 380 V AC rated voltage.
  • 10 × 38 mm fuse dimensions.
  • aM partial-range motor protection characteristic.
  • Integrated striker for fuse operation indication.
  • Ceramic insulating body.
  • Silver-plated copper terminal contacts.

Reliable Protection for Industrial Motor Circuits

The Mersen FR10AM40V20P is designed to protect motor circuits against damaging short-circuit currents. Its aM characteristic accommodates the temporary current surge produced during motor starting while responding rapidly to serious electrical faults.

The built-in striker provides a mechanical indication when the fuse-link has operated. When used with a compatible fuse holder and auxiliary contact, it can support remote fault indication, alarm circuits or control-system shutdown functions.

Typical Applications

  • Industrial motor starters.
  • Motor control centres.
  • Machinery and production equipment.
  • Electrical control panels.
  • Contactors and motor protection assemblies.
  • OEM automation systems.
