Why Choose the ABB E9F10AM25 Cylindrical Fuse?
The ABB E9F10AM25 is a compact and reliable 25 A aM cylindrical fuse link designed primarily for short-circuit protection of motors and associated industrial electrical equipment. Identified by ABB as the E 9F10 AM25 with order code 2CSM256283R1801, it forms part of the ABB E 9F range of cylindrical fuses for fuseholders and fuse switch disconnectors.
The fuse uses the standard 10.3 × 38 mm cylindrical format and has an aM utilisation category with delayed operating characteristics suited to motors with high starting currents. This enables the fuse to withstand normal motor-starting inrush while providing effective protection against damaging short-circuit currents.
With a rated current of 25 A, rated voltage of 400 V AC and breaking capacity of 120 kA, the E9F10AM25 provides dependable protection for demanding motor circuits. It is suitable for compatible 10.3 × 38 mm fuseholders and fuse switch disconnectors used in industrial control panels, machinery and motor-control systems.

Reliable Short-Circuit Protection for Motor Circuits
aM fuse links are designed primarily for short-circuit protection of motors and associated switching equipment. Their delayed operating characteristics accommodate the temporary high currents produced during motor starting while enabling high fault currents to be interrupted rapidly when a short circuit occurs.
Because an aM fuse provides partial-range protection, it is normally combined with suitable overload protection such as a thermal overload relay or electronic motor protection device. The ABB E9F10AM25 provides this short-circuit protection in the compact 10.3 × 38 mm cylindrical format.
