This means it handles the high inrush current and transient recovery voltage characteristic of capacitive loads — a standard power contactor would weld its contacts switching a capacitor bank of this size. Depth is 135 mm, height 100 mm — allow clearance for the arc chamber and wiring. IP20 on the front (finger-safe), IP00 at the terminals — the connection points are live when powered, so the panel door or a terminal cover must provide the final touch protection. ## Wiring and Auxiliary Contacts Main circuit uses screw-type terminals for 3-pole NO contacts. One auxiliary NO contact (screw-type) is built in — enough to signal the contactor state to a PLC input or to seal in the coil circuit. No NC auxiliary contacts on this variant.","metaTitle":"Siemens 3RT1627-1AN61 Capacitor Contactor, 35 A, 200 V AC Co","metaDescription":"Siemens SIRIUS 3RT1627-1AN61 capacitor contactor for AC-6 switching of 25 kVAr at 400 V. 35 A rated, 200 V AC coil.

It shares the same DIN-rail footprint and functional class; match the coil voltage and capacitor kVAr rating to select the correct 3RT2 variant."},{"question":"How do I source this phased-out contactor?","answer":"We source it to order against an RFQ. Provide your quantity and delivery window, and we'll check available surplus and distributor inventory across our network."},{"question":"What are the key ratings for this part?","answer":"AC-6 capacitor switching: 25 kVAr at 400 V. Rated operational current 35 A. Coil 200 V AC, 50/60 Hz. IP20 front, IP00 terminals. Screw terminals for main and auxiliary circuits.

However, the 3RT1627-1AN61 is a capacitor contactor with a 200 V AC coil, while the 3RT1023-1AL20 is a standard power contactor with a 230 V AC coil. The coil voltage and switching duty differ — verify your control voltage and load type before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1627-1AN61","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT1627-1AN61 when reusing this data.
