Why Choose the Mersen FR10AM50V1I Cylindrical Fuse with Visual Indicator?

The Mersen FR10AM50V1I is a compact 10 × 38 mm aM cylindrical fuse-link with visual indicator designed to provide dependable short-circuit protection for motor circuits, installation switchgear and industrial control equipment. As part of the established Mersen FR10 aM fuse range, it combines effective current limitation with clear visual fuse-status indication.

Its aM partial-range operating characteristic allows the fuse to withstand normal motor starting currents while rapidly interrupting dangerous short-circuit currents. The ceramic body and silver-plated copper contacts provide reliable thermal performance, electrical conductivity and long-term durability in demanding industrial environments.

With a rated current of 1 A, an IEC rated voltage of 500 V AC and a high 120 kA breaking capacity, the FR10AM50V1I is suitable for low-current motor control circuits and associated switchgear. The integrated visual indicator helps maintenance engineers identify an operated fuse quickly and reduce fault-finding time.

Key Advantages

  • Designed specifically for motor circuit short-circuit protection.
  • 1 A rated current for low-current control and motor applications.
  • 500 V AC IEC rated voltage.
  • 120 kA breaking capacity for effective fault interruption.
  • Integrated visual indicator for rapid identification of an operated fuse.
  • Compact 10 × 38 mm format for space-conscious control panels.

Key Features

  • Mersen FR10 aM cylindrical fuse range.
  • 10 × 38 mm cylindrical fuse-link.
  • 1 A rated current.
  • 500 V AC rated voltage.
  • aM partial-range motor protection characteristic.
  • Integrated visual blown-fuse indicator.
  • High-strength ceramic insulating body.
  • Silver-plated copper ferrule contacts.

Reliable Motor Circuit Protection with Visual Indication

The Mersen FR10AM50V1I helps protect motor circuit switchgear and associated electrical components from destructive short-circuit currents. Its current-limiting action reduces peak fault current and thermal energy, helping minimise damage to contactors, cables and control equipment.

The integrated visual indicator provides a clear local indication when the fuse has operated, allowing maintenance personnel to locate the affected circuit quickly. As an aM partial-range fuse, the FR10AM50V1I should be used with a suitable overload relay, motor protection relay or motor circuit breaker where overload protection is required.

Typical Applications

  • Low-current motor starter circuits.
  • Industrial control panels.
  • Motor control centres and switchgear.
  • Contactors and motor protection assemblies.
  • OEM machinery and automation equipment.
  • Fuse monitoring and maintenance applications.
