Why Choose the Mersen FR10AM50V20I Cylindrical Fuse-Link?
The Mersen FR10AM50V20I is a high-quality 10 × 38 mm aM cylindrical fuse-link with visual indicator designed to provide reliable short-circuit protection for industrial motor circuits. Manufactured by Mersen for IEC low-voltage applications, it is well suited to motor starters, control panels, machinery and automation equipment requiring dependable protection against high fault currents.
As part of the established Mersen FR10 aM fuse-link range, the FR10AM50V20I features a robust ceramic body and silver-plated contacts for consistent electrical performance and long service life. Its aM operating characteristic allows normal motor starting currents to pass while rapidly interrupting dangerous short-circuit currents that could damage motors, contactors and associated control equipment.
With a rated current of 20 A, a rated voltage of 500 V AC and a compact 10 × 38 mm format, the FR10AM50V20I is suitable for space-conscious industrial installations. Its integrated visual indicator also allows maintenance personnel to identify an operated fuse quickly during inspection and fault finding.
