It provides two normally open (2 NO) instantaneous contacts for signaling or control logic, wired via screw-type terminals. The switch is rated for a maximum continuous current of 2.5 A, with voltage-dependent switching capacity: 1 A at 24 V, 0.5 A at 230 V, 0.3 A at 48 V, and 0.15 A at 60 V. The switch plugs into the front of the breaker via a plug-in fixing — no DIN rail or separate mounting required. Its dimensions are 45 mm wide, 12 mm high, and 17 mm deep, matching the breaker's front profile. Wire termination accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded conductors, or 2x AWG 20–14 with ferrules.","metaTitle":"Siemens 3RV5901-1F SIRIUS Auxiliary Switch, 2 NO, 2.5A","metaDescription":"Siemens 3RV5901-1F SIRIUS transverse auxiliary switch for S00-S3 breakers. 2 NO contacts, 2.5A max, 24V 1A.
