Application
3KF switch disconnectors with fuses protect against overload and short circuit as main control and EMERGENCY OFF switches of switchboards, power distribution boards, power supply and motor outgoing feeders. 3KF switch disconnectors with fuses are designed to switch the specified rated current on and off under load. At the same time, they provide a safety isolating function and isolating distance in all low-voltage circuits. All 3KF switch disconnectors with fuses are climate-proof and meet the requirements of IEC 60947-1, IEC 60947-3 and VDE 0660-107.
