Why Choose the Mersen FR8AM40V2 Cylindrical Fuse-Link?
The Mersen FR8AM40V2 is a compact aM cylindrical fuse-link designed to provide dependable short-circuit protection for motors, motor starters and associated industrial electrical equipment. As part of the proven Mersen 8 × 32 mm ferrule fuse range, it is specifically engineered for motor circuits operating on systems up to 400 V AC.
Its aM partial-range characteristic enables the fuse-link to withstand the temporary inrush currents produced during motor starting while rapidly interrupting dangerous short-circuit currents. The FR8AM40V2 should be used in conjunction with a suitable overload relay or electronic motor protection device to provide complete motor protection.
With a 2 A rated current, a compact 8 × 32 mm cylindrical format and a 20 kA AC breaking capacity, the FR8AM40V2 is ideally suited to industrial control panels, OEM machinery and compact motor control applications.
