2CSM257523R1801 ABB E9F14AM25 E 9F14 AM25 Cylindrical Fuse 25 A 14 x 51 mm aM

Why Choose the ABB E9F14AM25 Cylindrical Fuse?

The ABB E9F14AM25 is a 25 A aM cylindrical fuse link designed for the protection of industrial motor circuits and other applications with high starting currents. Identified by ABB as the E 9F14 AM25 with order code 2CSM257523R1801, it forms part of the ABB E 9F aM range of cylindrical fuses.

The fuse uses the standard 14 × 51 mm cylindrical format and features an aM utilisation category. Its delayed operating characteristic is particularly suited to industrial motors, allowing the temporary high inrush current associated with motor starting while providing effective protection against short-circuit faults.

With a rated current of 25 A, rated voltage of 690 V AC and breaking capacity of 120 kA, the E9F14AM25 provides high fault-current interruption capability for demanding installations. It is designed for use with compatible 14 × 51 mm fuseholders and ABB E 90/50 fuse disconnectors.

Delayed Protection for Industrial Motor Circuits

ABB E 9F aM cylindrical fuses feature a delayed operating characteristic suited to industrial motors that draw high inrush currents during start-up. This allows normal starting current to pass without unnecessary fuse operation while maintaining high short-circuit interruption capability.

As an aM fuse, the E9F14AM25 is intended for motor-circuit protection and should be coordinated with the appropriate overload-protection equipment for the application. Its 25 A current rating, 690 V AC capability and 120 kA breaking capacity are provided in a compact 14 × 51 mm cylindrical format.
