Switch disconnector in new design Iu=400 A, Ue=690 V, 4-pole basic version w/o.

РАЗЪЕДИНИТЕЛЬ НОВОГО ДИЗАЙНА IU=400A, UE=690V, 4-ПОЛЮСА ОСНОВНОЕ ИСПОЛНЕНИЕ БЕЗ 8UC6 РУКОЯТКИ И ШТАНГИ 4 ПОЛ. ПЕРЕКЛЮЧАЕМЫЙ, AC-21A 3KA switch disconnectors up to 1000 A for low-voltage circuits. 3KA switch disconnectors are used as main, EMERGENCY OFF, maintenance and transfer switches in distribution boards for residential and non-residential buildings, and for industrial switchboards. As 3-pole and 4-pole versions, they ensure the making and breaking of the specified rated current under load. At the same time, they also provide a safety isolating function and isolating distance in all low-voltage circuits. Key features of the Siemens 3KA switch disconnectors: 1. Can be used in control cabinet side or back panels. 2. Comprehensive range of accessories for flexible retrofitting as required. 3. Compliance with IEC 60947-3, VDE 0660 Part 107 and Machinery Directive EN 60204-1. www.siemens.com/switching-devices. Siemens offers a comprehensive portfolio of protection, switching, measuring and monitoring devices, distribution systems as well as switches and sockets for safe and efficient electrical infrastructure in buildings and industry.
