That AC-6 duty class means it's designed to handle the inrush current from power-factor correction capacitor banks without welding the contacts. The coil pulls 200 V AC at both 50 and 60 Hz, so it lands on a standard control transformer secondary in European panels. ## Lifecycle and replacement This order code is a phased-out product. The manufacturer's designated successor is the SIRIUS 3RT2 series, with preferred replacement type 3RT2636-1NP35. The official successor is a drop-in functional replacement for new designs, but verify the coil voltage and auxiliary contact configuration against your panel schematic before committing. The 70 mm width and 183 mm depth fit a standard S3-size contactor footprint — panel cutouts and gland-plate layouts for the SIRIUS 3RT1 family carry over. Protection is IP00 on the terminals and IP20 on the front with the cover or box terminal installed — so it's panel-internal only, not for washdown or outdoor use without an enclosure. RoHS compliance date is noted as 05/01/2012, indicating the part was RoHS-compliant from that date forward.","metaTitle":"Siemens 3RT1647-1AN61 Capacitor Contactor, AC-6 50 kVAr, 200","metaDescription":"Siemens SIRIUS 3RT1647-1AN61 capacitor contactor for AC-6 switching of 50 kVAr at 400 V. 200 V AC coil, 3 NO main contacts, 1 NO auxiliary.

AC-6 is the IEC utilization category for switching capacitor banks — the contactor is designed to handle the high inrush current and restrike voltage that come with capacitive loads, which a standard AC-3 motor contactor may not survive long-term."},{"question":"What coil voltage does 3RT1647-1AN61 need?","answer":"It requires 200 V AC at 50 Hz or 200...220 V AC at 60 Hz. The coil frequency range is 50...60 Hz. This is a standard European control voltage; verify your panel's control transformer taps before wiring."},{"question":"Will 3RT1647-1AN61 drop into a panel specified around 3RT1044-1FB46?","answer":"The 3RT1647-1AN61 shares the same 70 mm width and screw-and-snap-on DIN-rail mounting method, so the mechanical footprint is compatible. However, the coil voltage differs (200 V AC vs 24 V DC on the 3RT1044-1FB46), and the 3RT1647 is a capacitor contactor while the 3RT1044 is a general-purpose power contactor. The auxiliary contact count also differs (1 NO vs 2 NO/2 NC). Rewiring of the control circuit and possibly the main power circuit would be required."},{"question":"Where can I buy 3RT1647-1AN61?","answer":"This phased-out part is sourced through independent distribution channels.
