Description
DF Electric 22×58 mm aM Cylindrical Fuse Link
The DF Electric 22×58 aM is a low-voltage cylindrical fuse link designed for short-circuit protection in motor circuits, transformers, and other loads with high inrush currents. The fuse links are available in 22×58 mm size, with rated currents from 2 to 125 A and rated voltages of 690 V AC, 500 V AC, and 400 V AC, depending on the current rating and reference.
They feature an aM operating class and are available without an indicator, with an indicator, or with a striker. The fuse links comply with IEC/EN 60269-1, IEC/EN 60269-2, and RoHS requirements.
