The 3KA and 3KE switch-disconnectors are used as main control switches, emergency stop, maintenance and transfer switches in distribution boards for residential and non-residential buildings as well as industrial switchgear assemblies. As three- and four-pole versions, they ensure the switching on and off of the specified rated current under load. At the same time, they provide a safety isolation function and isolation distance in all low-voltage circuits. All 3K switch-disconnectors are climate proof and meet the requirements of IEC 60947-1, IEC 60947-3 and VDE 0660 Part 107. The switch-disconnectors in the approved 8HP moulded plastic housing (protection class IP65) are available for use as safety switches.
