2CSM256373R1801 ABB E9F10AM12 E 9F10 AM12 Cylindrical Fuse 12 A 10.3 x 38 mm aM

Why Choose the ABB E9F10AM12 Cylindrical Fuse?

The ABB E9F10AM12 is a compact and reliable 12 A aM cylindrical fuse link designed primarily for the protection of industrial motor circuits with high starting currents. Identified by ABB as the E 9F10 AM12 with order code 2CSM256373R1801, it forms part of the ABB E 9F range of cylindrical fuses for compatible fuseholders and fuse switches.

The fuse uses the standard 10.3 × 38 mm cylindrical format and has an aM utilisation category with delayed tripping characteristics. This makes it particularly suitable for motor applications where temporary high inrush currents occur during starting while dependable protection against high fault currents is required.

With a rated current of 12 A, rated voltage of 500 V AC and breaking capacity of 120 kA, the E9F10AM12 provides robust protection for demanding industrial installations. Its compact format allows straightforward integration into compatible 10.3 × 38 mm fuseholders used in control panels, machinery and motor-control systems.
