ABB OTDC630FV22 630 A, 1500 V DC switch disconnector with 4-pole double-circuit configuration for photovoltaic, battery energy storage and industrial DC isolation.
The ABB OTDC630FV22 (SKU 1SCA158307R1001) is a premium DC switch disconnector engineered for the safe isolation of high-current direct current circuits in utility-scale photovoltaic (PV) power plants, battery energy storage systems (BESS) and industrial DC applications. As part of ABB's latest OTDC switch disconnector range, it has been specifically developed for modern 1500 V DC renewable energy installations, delivering exceptional switching performance, compact dimensions and outstanding long-term reliability.
Featuring a 4-pole double-circuit (4a / 4c) configuration, the OTDC630FV22 enables two photovoltaic strings to be safely isolated using a single compact switch. Its optimised contact design reduces switching losses while allowing manufacturers to reduce the size of combiner boxes and inverter assemblies, improving both efficiency and installation costs. Phase barriers are supplied as standard, while compatible operating handles and shafts are available separately.
With a 630 A DC-21B rated operational current, 500 A DC-PV2 rating, 1500 V DC operating voltage and compliance with IEC 60947-1 and IEC 60947-3, the OTDC630FV22 provides dependable DC isolation for the most demanding renewable energy infrastructure and industrial DC systems.
The ABB OTDC630FV22 has been specifically developed for large-scale 1500 V DC photovoltaic systems where higher operating voltages improve overall efficiency and reduce cable losses. Its compact double-circuit architecture enables engineers to reduce the size of combiner boxes and inverter cabinets while maintaining dependable DC isolation and outstanding electrical performance.
As part of ABB's advanced OTDC M-Series, the OTDC630FV22 offers excellent electrical endurance, reduced switch losses and reliable long-term operation, making it an ideal choice for renewable energy developers, OEM panel builders and industrial DC system integrators.
