ABB Medium Voltage MV Fuses

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

 

ABB high voltage fuse links type CMF are specially designed for motor circuit applications. ABB CMF fuses are tested according to the IEC Publication 60282-1 (IEC 282-1) and Publication 60644 (IEC 644). IEC 60644 applies to fuse links used with high voltage motors that are started direct-on-line in alternating current systems.

High voltage fuses used in motor circuits must be able to withstand, without deterioration, the repeated surges associated with motor starting.

ABB high voltage fuses 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 the ABB CMF high voltage fuses make them especially suitable in compact contactor compartments.

ABB CMF Motor Circuit Fuses Features

• Specially designed for motor circuit protection
• Tested according to IEC 60644 which guarantees excellent ability to withstand repeated motor starting conditions
• High current rating within single body dimensions
• Low minimum breaking current
• Low power losses, specially suitable in compact contactor compartments
• High breaking capacity
• Available with BS tags
• High current limitation
• Versions CMF-TCU equipped with Temperature Control Unit, which protects against high temperature in enclosed compartments
• Equipped with medium type striker, which is activated immediately when the fuse-elements melt
