2CSM277063R1801 ABB E9F8AM2 2 A 400 V AC 8.5 x 31.5 mm aM Cylindrical Fuse

Why Choose the ABB E9F8AM2 Cylindrical Fuse?

The ABB E9F8AM2 is a compact 2 A aM cylindrical fuse link designed for the protection of industrial motor circuits and associated electrical equipment. Part of the ABB E 9F aM cylindrical fuse range, it uses an 8.5 × 31.5 mm format and is designed for applications where high motor starting currents must be accommodated.

Featuring an aM utilisation characteristic, the E9F8AM2 has a delayed tripping curve suited to industrial motors with high inrush current during starting. It is typically used as part of a coordinated motor-protection arrangement, with suitable overload protection provided by the associated motor-protection equipment.

With a rated current of 2 A and rated voltage of 400 V AC, the E9F8AM2 provides a compact solution for motor and machinery circuits. ABB order code 2CSM277063R1801 identifies this specific fuse link within the ABB Protection & Control portfolio.

Reliable Protection for Industrial Motor Circuits

ABB E 9F aM cylindrical fuses feature a delayed tripping characteristic designed for motor applications where temporary high inrush currents occur during starting. This allows the motor to start normally while the fuse contributes to protection against damaging fault conditions.

The E9F8AM2 combines this motor-oriented operating characteristic with a compact 8.5 × 31.5 mm body, a 2 A current rating and a 400 V AC voltage rating. It is suited to coordinated protection arrangements in motor starters, industrial machinery and automation equipment.

Typical Applications

• Industrial motor circuits and motor starters.
• Pumps, fans and ventilation equipment.
• Conveyor and material handling systems.
• Production and processing machinery.
• Motor-control and automation panels.
• Industrial equipment with coordinated overload protection.
