ABB OTDC630FV02 two-pole DC switch disconnector rated at 630 A and 1500 V DC for utility-scale photovoltaic power plants, combiner boxes and inverter systems.
The ABB OTDC630FV02 (Product ID 1SCA158248R1001) is a compact, high-performance DC switch disconnector designed for reliable circuit isolation in utility-scale photovoltaic power plants. Part of the advanced ABB OTDC series, it is optimised for high-voltage solar installations requiring efficient and dependable switching at up to 1500 V DC.
This two-pole switch disconnector incorporates an efficient switching concept that can help reduce power losses and support more compact combiner box and inverter designs. Its robust construction and proven ABB engineering make it suitable for demanding renewable energy environments where operational safety, space efficiency and long service life are essential.
With a rated operational current of 630 A and a maximum operational voltage of 1500 V DC, the OTDC630FV02 is designed to disconnect a single photovoltaic circuit. It is approved in accordance with IEC 60947-1 and IEC 60947-3, supporting integration into professionally designed solar power equipment and DC distribution systems.
High-voltage photovoltaic systems require dependable switching devices capable of safely isolating DC circuits during maintenance, inspection and emergency procedures. The ABB OTDC630FV02 is specifically engineered for these applications, providing reliable switching performance in installations operating at up to 1500 V DC.
The compact OTDC design helps equipment manufacturers reduce the overall dimensions of solar combiner boxes and inverter systems. Its two-pole switching concept also supports improved system efficiency by reducing switch losses compared with conventional high-voltage DC switching arrangements.
