Why Choose the Mersen FR14AM50V12P Cylindrical Fuse-Link?
The Mersen FR14AM50V12P is a high-performance aM cylindrical fuse-link with striker designed to provide dependable short-circuit protection for motors, motor starters and associated industrial switchgear. As part of the trusted Mersen 14 × 51 mm ferrule fuse range, it is specifically engineered for motor circuits operating on systems up to 500 V AC.
Its aM partial-range characteristic allows the fuse-link to withstand the temporary inrush currents generated during motor starting while rapidly disconnecting high short-circuit fault currents. The integrated striker mechanism enables operation of a compatible auxiliary contact, providing convenient remote indication whenever the fuse operates. All Mersen cylindrical aM fuse-links feature ceramic bodies and silver-plated contacts for dependable long-term performance.
With a 12 A rated current, a standard 14 × 51 mm cylindrical format and a high 120 kA breaking capacity, the FR14AM50V12P is ideal for industrial motor control centres, machinery, OEM equipment and automation systems requiring reliable motor circuit protection.
