Application
3KD switch disconnectors are designed for applications with exacting requirements. They are deployed as main control switches, EMERGENCY OFF switches and repair switches in industrial plants, infrastructure and buildings. 3KD switch disconnectors 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 3KD switch disconnectors are climate-proof and meet the requirements of IEC 60947-1, IEC 60947-3 and VDE 0660-107.
