Rated for 22 A maximum ampacity and 690 V insulation voltage at pollution degree 3, it handles the main circuit feed for motor starter combinations up to that current ceiling. ## Panel fit — the 28.4 mm depth matters for DIN-rail clearance At 28.4 mm deep, 25.9 mm wide, and 30.4 mm tall, this terminal block is compact enough to sit flush against the contactor without protruding past the DIN rail envelope — important when the panel backplate is tight against the enclosure door. The S00 contactor size is the smallest Siemens SIRIUS frame, so the infeed terminal matches that footprint — no wasted rail space in a multi-starter lineup. ## Wire termination — what the conductor ranges actually cover Solid wire acceptance is 1x (2.5 to 6.0 mm²) — a single conductor per clamp, not parallel feeds. Stranded wire range is 2.5 to 6 mm², and finely stranded with ferrule goes up to 10 mm². AWG equivalents for the main contacts are 12 to 8 AWG — common for 22 A motor branch circuits on 480 V or 400 V systems. ## Environmental limits and compliance Operating temperature range is -40 to +60 °C, storage range is -50 to +80 °C — suitable for unheated control cabinets in temperate or cold climates. Substance prohibitance date of 10/01/2009 aligns with RoHS compliance — the terminal meets the EU substance restrictions for industrial equipment.","metaTitle":"Siemens 3RA2913-3K 3-phase infeed terminals, 22 A, S00","metaDescription":"Siemens SIRIUS 3RA2913-3K 3-phase infeed terminals for 3RT201 contactors. 22 A ampacity, S00 size, screw-type box terminals.
