£0.63
The Mersen FR10AM50V4 is a high-performance 10×38 mm aM cylindrical fuse-link designed to provide dependable short-circuit protection for motor circuits and industrial electrical equipment. Manufactured by Mersen, this fuse forms part of the trusted FR10 aM series, offering exceptional current limiting performance and reliable protection for motor starters, switchgear and industrial control panels.
Designed in accordance with IEC standards, the FR10AM50V4 features a robust ceramic body with silver-plated contacts for excellent electrical conductivity and long service life. As an aM partial-range fuse, it is specifically engineered to protect motors against high fault currents whilst allowing normal motor starting currents to pass without nuisance operation.
With a 4 A current rating, 500 V AC rated voltage and 120 kA breaking capacity, this industrial fuse delivers reliable protection for demanding applications where motor circuits require high fault interruption capability.
The Mersen FR10AM50V4 is designed to protect motors, contactors and associated switchgear from destructive short-circuit currents. Its aM operating characteristic permits the high inrush current required during motor starting whilst rapidly clearing dangerous fault currents before equipment damage occurs.
Its compact 10 × 38 mm format makes it suitable for installation in industrial control panels, machinery and OEM equipment where dependable motor protection and compliance with international standards are essential.
