2CSM277283R1801 ABB E9F8AM1 E 9F8 AM1 Fuse 1 A 8.5 × 31.5 mm aM

Why Choose the ABB E9F8AM1 Cylindrical Fuse?

The ABB E9F8AM1 is a compact 1 A cylindrical aM fuse designed for protection of industrial motor circuits and associated motor-control equipment. Part of the ABB E 9F8 aM cylindrical fuse series, the E 9F8 AM1 combines a motor-oriented delayed operating characteristic with the compact 8.5 × 31.5 mm cylindrical fuse format.

Featuring an aM utilisation category, the E9F8AM1 is designed for motor applications where temporary high inrush currents occur during starting. Its delayed operating characteristic allows appropriately coordinated motor starting currents while providing protection against damaging fault currents, with separate overload protection normally incorporated into the complete motor protection system.

With a rated current of 1 A, a rated voltage of 400 V AC and a 20 kA breaking capacity, the E9F8AM1 provides dependable protection in a particularly compact package. Its standard 8.5 × 31.5 mm dimensions enable installation in compatible cylindrical fuseholders and fuse switch disconnectors.
