ABB CMF Motor Fuses - IEC Standard 3.6kV-12kV

ABB MV HV Medium - High Voltage Fuses

Indoor Fuses for MV Medium Voltage Cable Networks

ABB CMF Motor Fuses - IEC Standard 3.6kV-12kV

 

ABB CMF Motor Fuses are specially designed for medium voltage (MV) or high voltage (HV) motor circuit applications from 3.3kV (3.6kV up to 11kV (12kV). Motor fuses are tested to IEC Publication 60282-1 (IEC 282-1) and Publication 60644 (IEC 644). IEC 60644 applies to fuse links used with motors that are started direct-on-line in alternating current (AC) systems. High voltage fuses used in motor circuits must be able to withstand, without deterioration, the repeated surges associated with motor starting.

Motor fuse dimensions are in accordance with DIN 43625 and IEC 60282-1.

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 ABB CMF Motor Fuses make them especially suitable in compact contactor compartments.
