ABB OTHV400E04W four-pole 400A switch disconnector for 800–1000 V AC industrial electrical isolation.
The ABB OTHV400E04W, product code 1SCA162984R1001, is a heavy-duty four-pole switch disconnector designed to provide safe electrical isolation and dependable switching in industrial systems operating between 800 and 1000 V AC. As part of the ABB OTHV high-voltage switch disconnector range, it is engineered for demanding applications including industrial power distribution, renewable energy systems, switchboards and automation equipment.
This front-operated, base-mounted switch disconnector offers robust manual isolation while allowing installers to select the most suitable external operating mechanism for their enclosure. The operating handle and shaft are supplied separately, providing maximum installation flexibility for OEMs, panel builders and electrical contractors.
With a 400 A conventional thermal current, four switched poles and a 12 kV impulse withstand voltage, the OTHV400E04W delivers reliable performance for high-voltage industrial applications while meeting the requirements of IEC 60947-3.
The ABB OTHV400E04W is designed to safely isolate high-voltage electrical circuits before maintenance, inspection or servicing. Its four-pole design allows simultaneous isolation of all conductors, making it suitable for industrial switchboards, machinery and renewable energy systems where dependable isolation is essential.
Its modular design allows installers to pair the switch with ABB operating shafts and handles that best suit the enclosure, making it a flexible solution for OEM equipment, electrical panels and industrial installations.
