2CSM257473R1801 ABB E9F10AM05 E 9F10 AM05 Cylindrical Fuse 0.5 A 10.3 x 38 mm aM

Why Choose the ABB E9F10AM05 Cylindrical Fuse?

The ABB E9F10AM05 is a compact 0.5 A aM cylindrical fuse link designed for motor protection applications where a delayed fuse characteristic is required. Identified by ABB as the E 9F10 AM05 with order code 2CSM257473R1801, it forms part of the ABB E 9F aM range of cylindrical fuses.

The fuse uses the standard 10.3 × 38 mm cylindrical format and features an aM utilisation category. ABB's aM range is designed with delayed operating characteristics for motor circuits, allowing normal starting inrush currents to pass while providing high short-circuit interruption capability.

With a rated current of 0.5 A, rated voltage of 500 V AC and breaking capacity of 120 kA, the E9F10AM05 provides dependable protection in compact motor-control applications. Its standard cylindrical construction enables straightforward use with compatible 10.3 × 38 mm fuseholders and fuse disconnectors.

Delayed Protection for Motor Circuits

aM cylindrical fuses are intended for motor applications where substantial temporary inrush currents can occur during starting. Their delayed operating characteristics help prevent unnecessary fuse operation during normal start-up while retaining the ability to interrupt high short-circuit fault currents.

As an aM partial-range fuse, the E9F10AM05 should be coordinated with suitable overload protection where required by the motor circuit design. Its 0.5 A rating, 500 V AC capability and 120 kA breaking capacity are provided in the compact 10.3 × 38 mm cylindrical format.

Typical Applications

• Low-current motor protection circuits.
• Industrial motor-control panels.
• Motor starters and associated control equipment.
• Industrial automation systems.
• Machinery control circuits.
• Pumps, fans and motor-driven equipment.
• OEM motor-control assemblies.
