Why Choose the ABB E9F14AM45 Cylindrical Fuse?
The ABB E9F14AM45 is a robust 45 A aM cylindrical fuse link designed for protection of industrial motor circuits and other loads with high starting currents. Identified by ABB as the E 9F14 AM45 with order code 2CSM257433R1801, 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 with delayed tripping characteristics. This allows normal motor-starting inrush currents to pass while providing effective protection against overload and short-circuit conditions when correctly coordinated within the motor circuit.
With a rated current of 45 A, rated voltage of 500 V AC and breaking capacity of 120 kA, the E9F14AM45 is suited to demanding industrial installations. Its compact cylindrical construction is designed for use with compatible ABB E 90/50 fuse disconnectors and suitable fuseholders.
