The switch plugs into the breaker with a plug-in fixing — no tools needed to snap it on, which saves time on a build where you're populating a row of breakers. At 17 mm deep and 45 mm wide it stays inside the breaker's own footprint, so it doesn't eat into DIN-rail clearance for adjacent devices. ## Ratings that matter for the control circuit The contacts are rated for 2.5 A maximum at AC-12 duty — that's the resistive-load rating for control circuits, so it handles pilot lights, PLC inputs, and relay coils within that current. At 24 V it switches 1 A; at 48 V it drops to 0.3 A; at 60 V it's 0.15 A; at 230 V it handles 0.5 A. These are the actual switching limits at those voltages, not just thermal ratings. The screw-type terminals accept two conductors per clamp — 0.5 to 1.5 mm² solid or finely stranded with ferrules, or 0.75 to 2.5 mm². AWG 20 to 14 fits. That's enough for daisy-chaining common and signal wires without extra terminal blocks. RoHS compliance date of May 1, 2012 means it's free of the original six restricted substances; REACH and other EU chemical regulations apply per Siemens standard declarations.","metaTitle":"Siemens 3RV6901-1E SIRIUS Auxiliary Switch, 1 NO + 1 NC, 17","metaDescription":"Siemens 3RV6901-1E SIRIUS transverse auxiliary switch for S00–S3 breakers. 1 NO + 1 NC contacts, 2.5 A AC-12 max.
