The ABB DC Switch-Disconnectors / OTDC25U catalog features PV disconnect switches designed for DC applications. These switches include a terminal bolt kit and require separate ordering of handles and shafts. Mounting options include base and door mounting, with some models incorporating a US single-wire break functionality. They are rated for various DC voltage levels, including UL 600 VDC, IEC 660 VDC, and IEC 1000 VDC, with current ratings up to 25 A for double circuit and 16 A for single circuit configurations.
