It is rated AC-6 at 50 kVAr / 400 V, 50 Hz, with three main poles and one normally-open auxiliary contact. The coil is AC-operated at 400 V, 50 Hz. AC-6 duty is the standard utilisation category for switching capacitor loads — the contactor must handle high inrush currents without welding its contacts. The 50 kVAr rating at 400 V means it can switch a capacitor bank of that size in a typical 400 V three-phase network. The 90 A rating at AC-1 (resistive) confirms the contactor's thermal capacity. Side-by-side mounting is permitted with no gap. The contactor is 70 mm wide, 167 mm tall, and 183 mm deep — Size S3 footprint. Main and auxiliary circuits use screw-type terminals. The front face carries IP00 protection; IP20 is achieved only with the supplied cover or box terminal installed. The substance prohibitance date of 05/01/2012 indicates RoHS compliance from that date forward. No UL or CSA listing is stated in the available specs — verify with your local Siemens office if those marks are required for your jurisdiction.","metaTitle":"Siemens 3RT1647-1AV01 Capacitor Contactor, AC-6 50 kVAr, 400","metaDescription":"Siemens SIRIUS 3RT1647-1AV01 capacitor contactor, AC-6 rated 50 kVAr at 400 V, 50 Hz, 3-pole, Size S3.
