The cage clamp termination means you land solid or stranded wire without a screwdriver — the spring holds the conductor against the bus bar. Wires up clean in a control station, no torque spec to chase. Lifecycle stage is listed as 'current' — Siemens still produces this GM-SET operator as an active line item. Sourced through independent distribution against an RFQ. ## Where it lands in the panel This operator mounts as the control station interface for a Siemens SIRIUS 3RA2 or 3RA5 motor starter — it's the pushbutton that gives the operator a mushroom-head emergency-stop or start function with illumination. The blue lens signals a specific machine state (typically 'ready' or 'reset'), not a standard red stop. The push-pull actuation means you push to latch, pull to release — common for maintained emergency-stop circuits where the button stays depressed until manually reset. The 1NO+1NC contact block gives both a normally-open and normally-closed signal path, so you can wire both the safety circuit (NC) and the status indication (NO) from one operator.","metaTitle":"Siemens 3RA9012-5BM38 GM-SET Pushbutton, Mushroom, Blue","metaDescription":"Siemens 3RA9012-5BM38 GM-SET pushbutton operator: mushroom head, illuminated blue, push-pull, 1NO+1NC, cage clamp.
