ABB OTDC400FV22 400 A, 1500 V DC switch disconnector with 4-pole double-circuit configuration for photovoltaic, battery energy storage and industrial DC isolation.
The ABB OTDC400FV22 (SKU 1SCA158299R1001) is a high-performance DC switch disconnector designed 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. Part of ABB's latest OTDC switch disconnector range, it has been specifically engineered for modern 1500 V DC renewable energy systems, offering exceptional reliability, reduced footprint and improved electrical efficiency.
The OTDC400FV22 features a 4-pole double-circuit (4a / 4c) configuration, allowing two PV strings to be isolated using a single compact switch. Its optimised contact design reduces switch power losses while enabling manufacturers to build smaller combiner boxes and inverter cabinets, making it ideal for next-generation utility-scale solar projects. Handles and shafts are supplied separately, while mandatory phase barriers are included.
Rated at 400 A with an operational voltage of 1500 V DC, the OTDC400FV22 delivers dependable switching performance, excellent mechanical endurance and full compliance with IEC 60947-1 and IEC 60947-3 standards for demanding DC isolation applications.
The ABB OTDC400FV22 has been developed specifically for modern 1500 V DC photovoltaic installations, enabling engineers to reduce equipment size while improving system efficiency. Its compact four-pole architecture simplifies combiner box and inverter design without compromising switching safety or electrical performance.
As part of ABB's latest OTDC generation, the OTDC400FV22 delivers excellent electrical endurance, dependable DC switching and long-term operational reliability for renewable energy infrastructure, battery storage installations and industrial DC systems.
