Why Choose the ABB E9F14AM6 E 9F14 AM6 Fuse?
The ABB E9F14AM6, type code E 9F14 AM6, is a 14 × 51 mm cylindrical aM fuse link designed specifically for short-circuit protection of industrial motor circuits. 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 6 A, the E 9F14 AM6 combines a 690 V AC rated voltage with a high 120 kA maximum breaking capacity. Its aM utilisation category provides partial-range protection focused on short-circuit faults, making it suitable for coordination with a separate overload relay or motor protection device.
The E9F14AM6 has a power loss of just 0.42 W at rated operating conditions and uses robust ceramic construction with silver-plated copper contacts. Its standard 14 × 51 mm dimensions allow straightforward integration with compatible cylindrical fuseholders and fuse-switch disconnectors in motor control and industrial automation systems.

Delayed Short-Circuit Protection for Motor Circuits
Industrial motors can draw substantially higher current during start-up than during normal operation. ABB E 9F aM fuse links use a delayed tripping characteristic that accommodates these temporary inrush currents while providing effective protection against short-circuit faults that could otherwise damage motors, conductors and switching equipment.
Because the aM classification provides partial-range protection focused on short-circuit faults, the ABB E 9F14 AM6 is normally coordinated with suitable separate overload protection. This combination makes it well suited to motor starters, machinery and industrial automation systems requiring high fault interruption capability without nuisance operation during normal motor starting.
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.
- Motor control centres and switchboards.
- Compatible 14 × 51 mm cylindrical fuseholders and fuse-switch disconnectors.
