£841.16
The ABB OTDC630FV11 (Product ID 1SCA158250R1001) is a high-performance DC switch disconnector engineered for safe isolation of high-current direct current circuits in 1500 V DC utility-scale photovoltaic power plants. As part of the proven ABB OTDC series, it delivers exceptional switching performance while helping manufacturers reduce enclosure size and improve overall system efficiency.
Its innovative two-pole design reduces switch losses by up to 35% compared with conventional solutions while providing a compact footprint that enables smaller combiner boxes and inverter systems. Measuring only 150 mm wide and 122 mm high, the OTDC630FV11 helps maximise valuable enclosure space without compromising reliability or safety.
With a 630 A rated operational current, a 1500 V DC operating voltage and compliance with IEC 60947-1 and IEC 60947-3, this switch disconnector is ideally suited to utility-scale solar installations, industrial DC distribution equipment and renewable energy infrastructure. Handles and operating shafts are supplied separately.
The ABB OTDC630FV11 has been specifically developed to safely isolate high-current DC circuits within modern 1500 V photovoltaic installations. Its advanced switching mechanism improves system efficiency while providing dependable isolation during maintenance, servicing and emergency shutdown procedures.
Its compact dimensions, high current rating and ABB's proven engineering make it an ideal solution for panel builders, inverter manufacturers, EPC contractors and renewable energy system integrators requiring dependable DC isolation.
