ABB OTDC500FV22 500 A, 1500 V DC switch disconnector with 4-pole double-circuit configuration for photovoltaic, battery energy storage and industrial DC isolation.
The ABB OTDC500FV22 (SKU 1SCA158303R1001) is a premium DC switch disconnector developed 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 installations. As part of ABB's latest OTDC switch disconnector range, it has been specifically engineered for modern 1500 V DC renewable energy systems, delivering outstanding switching performance, compact dimensions and long-term reliability.
Featuring a 4-pole double-circuit (4a / 4c) configuration, the OTDC500FV22 enables the isolation of two photovoltaic strings using a single compact switch. Its optimised contact system reduces switch 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 handles and shafts are available separately.
With a 500 A rated operational current, 1500 V DC operating voltage and full compliance with IEC 60947-1 and IEC 60947-3, the OTDC500FV22 is ideally suited to demanding renewable energy infrastructure and industrial DC applications.
The ABB OTDC500FV22 has been developed specifically for modern 1500 V DC photovoltaic systems where higher operating voltages improve overall system efficiency and reduce cable losses. Its compact double-circuit architecture enables engineers to reduce the size of combiner boxes and inverter cabinets while maintaining safe, dependable DC isolation.
As part of ABB's latest OTDC generation, the OTDC500FV22 provides excellent electrical endurance, dependable switching performance and low maintenance, making it an ideal solution for renewable energy developers, OEM panel builders and industrial DC system integrators.
