ABB fuse links type CMF are specially designed for high voltage motor circuit
applications and are tested according to the IEC Publication 60282-1 (IEC 282-1) and Publication 644. The IEC 644 applies to HV fuse links used with motors that are started direct-on-line in alternating current system. High-voltage fuses used in motor circuits must be able to withstand, without deterioration, the repeated surges associated with motor starting.

The dimensions are in accordance with DIN 43625, i.e. the 3.6kV rating is realized in the normal 12 kV length (e = 292 mm). The 7.2 kV and 12 kV rating in the 24 kV length (e = 442 mm). Special connection elements can be delivered in cases where fuses have to be configured in parallel.

ABB CMF High Voltage motor fuses have the following properties:
-- higher current rating within single body dimensions
-- excellent ability to withstand repeated motor starting conditions
-- low power losses
-- low minimum breaking current
-- high breaking capacity and excellent short circuit current limitation

Although a motor fuse is normally run at a stationary current which is much lower than the fuse rated current, the low-loss characteristics of the ABB CMF fuses make them especially suitable in compact contactor compartments.
