Maximum switching rate is 180 operations per hour across all voltage ratings from 230 V to 690 V AC. ## DIN rail footprint and panel fit Size S00 frame, 45 mm wide by 125 mm tall by 120 mm deep. At 40 °C ambient, single 4 mm² or 2x 2.5 mm² is permitted; at 60 °C, 2x 4 mm². The coil terminals are screw-type as well. ## Temperature range and arc timing Arc duration is 10...15 ms with an AC arcing time of 4...15 ms — this matters when coordinating upstream short-circuit protection devices, as the let-through energy during capacitor switching can differ from resistive or motor loads.","metaTitle":"Siemens 3RT2617-1AB03 SIRIUS Capacitor Contactor, 45 mm","metaDescription":"Siemens 3RT2617-1AB03 SIRIUS capacitor contactor, size S00, 45 mm width, screw/snap-on DIN rail mount.
