ABB OTHV1000E04 four-pole switch disconnector for 800 to 1000 V AC industrial power distribution, featuring a 1600 A conventional thermal current and base-mounted front operation.
The ABB OTHV1000E04 (1SCA162922R1001) is a heavy-duty 4-pole switch disconnector designed to provide safe electrical isolation and reliable switching for high-current industrial power distribution systems. As part of the robust ABB OTHV switch disconnector range, it is engineered for demanding applications operating at 800 to 1000 V AC.
This front-operated, base-mounted switch disconnector combines high current capacity with dependable mechanical performance. Its four-pole configuration allows the switching of three phases and a neutral conductor, making it suitable for installations where complete circuit isolation is required during maintenance, servicing or emergency shutdown procedures.
With a 1600 A conventional thermal current, a 1000 A AC-21A and AC-22A operational current and an 800 A AC-23A operational current at 800 V AC, the OTHV1000E04 is ideal for industrial switchboards, power generation equipment, renewable energy systems and heavy-duty electrical distribution installations. The operating handle and shaft are not included and must be ordered separately.
The ABB OTHV1000E04 provides visible and dependable isolation of high-current electrical circuits, helping engineers and maintenance personnel work safely on de-energised equipment. Its robust switching mechanism is designed for reliable performance in industrial environments where system availability and operational safety are essential.
The four-pole arrangement enables the neutral conductor to be disconnected together with the three phase conductors. This makes the switch particularly suitable for generators, renewable energy equipment, distribution boards and installations where complete electrical separation is required.
