£1,237.87
The ABB OTDC800FV11 (Product ID 1SCA158856R1001) is a high-performance DC switch disconnector engineered for the safe isolation of high-current circuits in 1500 V DC utility-scale photovoltaic installations. Part of ABB's advanced OTDC M-Series, it combines a compact footprint, reduced power losses and exceptional switching performance to meet the demands of modern renewable energy systems.
Its fully optimised two-pole design helps manufacturers reduce the size of combiner boxes and inverter assemblies while improving system efficiency. Measuring only 150 mm wide and 122 mm high, the OTDC800FV11 occupies significantly less space than conventional solutions, allowing more compact equipment designs. Handles and operating shafts are supplied separately to suit installation requirements.
With an 800 A DC-21B rated operational current, 400 A DC-22B rating, 1500 V DC operating voltage and compliance with IEC 60947-1 and IEC 60947-3, the OTDC800FV11 provides dependable manual isolation for demanding photovoltaic applications.
The ABB OTDC800FV11 has been developed to safely isolate high-current DC circuits in photovoltaic combiner boxes, central inverter systems and industrial renewable energy installations. Its compact design and reduced switching losses help manufacturers produce smaller, more efficient equipment while maintaining dependable long-term performance.
Combining ABB's proven switching technology with robust construction, the OTDC800FV11 is an excellent choice for EPC contractors, inverter manufacturers, panel builders and renewable energy system integrators requiring reliable manual DC isolation.
