SPDT contact block for panel or DIN-rail switching
The ABB 1SVR405613R8200 is a CR-M relay with a single-pole double-throw (SPDT) contact arrangement, meaning it switches one circuit between normally-open and normally-closed positions — the standard building block for interposing, isolation, or signal-routing in a control panel. It sits in the General Purpose Relays category, so it is sized for the 5–10 A range typical of PLC output isolation, motor starter auxiliaries, or pilot-duty loads in a DIN-rail enclosure.
