The DC coil at 110 V gives you a pickup threshold of 0.85x rated and dropout at 1.1x — so it holds in during sags but drops cleanly on overvoltage without chattering. ## DIN-rail fit and wiring — 45 mm wide, screw terminals The 45 mm width and 120 mm depth leave room alongside other S00 devices in a crowded panel. No attachable auxiliary switch blocks come with it — you add them separately if needed. That helps when the gland plate forces the contactor into an odd angle. ## Switching performance and thermal limits Maximum switching frequency is 180 1/h across the entire voltage range from 230 V to 690 V, so it handles frequent bank switching in PFC duty. That covers most indoor panel environments, including unheated warehouses. ## Sourcing — active production, quoted to order Lifecycle stage is current — Siemens still produces this capacitor contactor.","metaTitle":"Siemens 3RT2617-1BF45 SIRIUS Capacitor Contactor","metaDescription":"Siemens 3RT2617-1BF45 SIRIUS capacitor contactor, DC coil 110 V, size S00, 45 mm wide.
