2CSM277313R1801 ABB E9F14AM12 E 9F14 AM12 Fuse 12 A 14 × 51 mm aM

Why Choose the ABB E9F14AM12 Cylindrical Fuse?

The ABB E9F14AM12 is a reliable 12 A cylindrical aM fuse designed specifically for short-circuit protection of motors and associated motor-control equipment. Part of the ABB E 9F14 aM cylindrical fuse series, the E 9F14 AM12 combines a motor-oriented operating characteristic with the standard 14 × 51 mm cylindrical fuse format.

Featuring an aM utilisation category, the E9F14AM12 provides partial-range protection for motor circuits. Its operating characteristic is designed to accommodate the temporary high inrush currents associated with motor starting, while overload protection is normally provided by a separate coordinated device such as a motor overload relay.

With a rated current of 12 A, a rated voltage of 690 V AC and a high 120 kA breaking capacity, the E9F14AM12 provides dependable protection for demanding industrial motor circuits. Its standard 14 × 51 mm dimensions enable straightforward installation in compatible cylindrical fuseholders and fuse switch disconnectors.

Reliable Short-Circuit Protection for Motor Circuits

aM cylindrical fuse links are specifically designed for motor applications where substantial temporary inrush currents can occur during starting. The ABB E9F14AM12 provides partial-range protection against short-circuit currents while allowing appropriately coordinated motor starting currents to pass without unnecessary fuse operation.

Because an aM fuse is intended primarily for short-circuit rather than full-range overload protection, the E9F14AM12 is normally coordinated with a suitable overload protective device. This makes it well suited to motor starter assemblies incorporating contactors, overload relays and compatible ABB fuseholders or fuse switch disconnectors.

Typical Applications

• Industrial motor circuits.
• Motor starters and control equipment.
• Pumps, fans and compressor systems.
• Conveyors and material handling machinery.
• Industrial automation and machinery control panels.
• OEM motor-control assemblies and production equipment.
