Coil pickup is 100–127 V at 50/60 Hz, with a dropout threshold around 85 % of rated voltage (0.85 initial value), and a recovery time of 150 ms before the coil can re-energize after drop-out. Clip-on fastening means it snaps directly onto the front or side of a SIRIUS contactor without tools — no DIN rail footprint consumed, but it does add 45 mm width and 75 mm depth to the contactor envelope.","metaTitle":"Siemens SIRIUS 3RT1916-2FK11 Auxiliary Switch, 3 A, 45 mm","metaDescription":"Siemens SIRIUS 3RT1916-2FK11 auxiliary switch, 3 A max, 45 mm wide, clip-on for contactors.
