Why Choose the ABB E9F8AM8 E 9F8 AM8 Fuse?
The ABB E9F8AM8, type code E 9F8 AM8, is a compact cylindrical aM fuse link designed specifically for short-circuit protection of industrial motor circuits. As part of the ABB E 9F aM cylindrical fuse range, it features a delayed operating characteristic that accommodates the high inrush currents associated with motor starting.
Rated at 8 A, the E 9F8 AM8 uses the compact 8.5 × 31.5 mm cylindrical format for installation in compatible fuseholders and fuse disconnectors. Its aM utilisation category provides partial-range protection focused on short-circuit faults and is intended to be coordinated with suitable overload protection in motor applications.
With a rated voltage of 400 V AC and a breaking capacity of 20 kA, the E9F8AM8 provides dependable fault interruption for compatible low-voltage motor circuits. Its small cylindrical construction and approximately 0.004 kg unit weight make it particularly suitable for compact motor control panels, machinery and industrial electrical equipment.

Reliable Short-Circuit Protection for Motor Circuits
Motor circuits can draw substantially higher current during starting than during normal operation. ABB E 9F aM cylindrical fuses use a delayed operating characteristic that accommodates these temporary inrush currents while providing effective interruption of short-circuit faults that could otherwise damage conductors, switching devices and motor equipment.
Because an aM fuse provides partial-range protection focused on short-circuit faults, the E 9F8 AM8 is normally coordinated with a suitable overload relay or motor protection device. Its compact 8.5 × 31.5 mm construction makes it an effective solution for motor starters and industrial control equipment where installation space is limited.
Typical Applications
- Industrial motor circuits.
- Motor starters and control panels.
- Pumps, fans and ventilation equipment.
- Conveyors and material handling systems.
- Manufacturing and processing machinery.
- Industrial automation equipment.
- Compact motor control and distribution panels.
- Compatible 8.5 × 31.5 mm cylindrical fuseholders and fuse disconnectors.
