The Omron 61F-03B is a 3-pole surge suppressor from the Series 61F line, classified as a controller accessory. It's designed to clamp voltage transients on the coil or switching element it parallels — common on level controller outputs or relay coils in the same family. Production status is Active per the manufacturer, so this isn't an obsolete hunt. The lifecycle stage is marked mature, meaning the design is stable and no further development is planned — typical for a long-running accessory that just works.
