2CSM256343R1801 ABB E9F14AM32 E 9F14 AM32 Fuse 32 A 14 × 51 mm aM

Why Choose the ABB E9F14AM32 E 9F14 AM32 Fuse?

The ABB E9F14AM32, type code E 9F14 AM32, is a high-performance cylindrical aM fuse link designed specifically for short-circuit protection of motors and associated electrical equipment. As part of the ABB E 9F cylindrical fuse range, it combines a compact format with a delayed operating characteristic suitable for industrial motor circuits with high starting currents.

Rated at 32 A, the E 9F14 AM32 uses the standard 14 × 51 mm cylindrical format for installation in compatible fuseholders and fuse-switch disconnectors. Its aM utilisation category is intended for motor protection applications, allowing temporary motor starting currents while providing high-capacity protection against short-circuit faults.

With a rated voltage of 500 V AC and a high breaking capacity of 120 kA, the E9F14AM32 provides dependable fault interruption in demanding low-voltage installations. Its low power loss and compact ceramic construction make it suitable for motor control panels, machinery and industrial distribution equipment.

Reliable Short-Circuit Protection for Motor Circuits

aM fuse links are designed for motor circuits where starting current can be considerably higher than the normal operating current. Their delayed operating characteristic accommodates these temporary inrush currents while providing rapid interruption of high short-circuit currents that could otherwise damage motors, conductors and switching equipment.

Because the aM classification provides partial-range protection focused on short-circuit faults, the E 9F14 AM32 is normally coordinated with suitable overload protection such as an overload relay or motor protection device. This makes it an effective protection component for motor starters, industrial machinery and automated production systems.
