Why Choose the ABB E9F10AM10 Cylindrical Fuse?
The ABB E9F10AM10 is a 10 A aM cylindrical fuse link designed specifically for short-circuit protection of motor circuits. Identified by ABB as the E 9F10 AM10 with order code 2CSM257553R1801, it forms part of the ABB E 9F range of cylindrical fuses for motor-protection applications.
The fuse uses the compact 10.3 × 38 mm cylindrical format and has an aM utilisation category. Its delayed protection characteristic is designed to accommodate the high inrush currents associated with motor starting while providing effective interruption of dangerous short-circuit currents.
With a rated current of 10 A, rated voltage of 500 V AC and maximum breaking capacity of 120 kA, the E9F10AM10 provides robust protection for industrial motor circuits. Its ceramic body and silver-plated copper contacts provide a durable construction for compatible cylindrical fuseholders and fuse disconnectors.
Key Advantages
- Purpose-designed aM fuse for motor short-circuit protection.
- 10 A rated current for appropriately coordinated motor circuits.

Delayed Protection for Motor Starting
aM cylindrical fuses are designed for short-circuit protection of motor circuits and provide delayed protection suitable for loads with substantial starting currents. This allows temporary motor-starting inrush to pass while retaining high fault-current interruption capability when a short circuit occurs.
Because the aM classification is intended for short-circuit rather than full-range overload protection, the E9F10AM10 is normally coordinated with suitable motor overload protection. Its 10 A rating, 500 V AC voltage capability and 120 kA maximum breaking capacity make it suitable for demanding industrial motor-control systems.
Typical Applications
- Industrial motor circuits.
- Motor starters and control panels.
- Motor control centres.
- Pumps, fans and compressors.
- Conveyor and material-handling systems.
- Industrial machinery and automation equipment.
- OEM motor-control assemblies.
