The 24 V coil draws its rated voltage at 50 Hz; the operating range spans -25 to +60 °C ambient, with storage from -55 to +80 °C. The arcing time is 10 ms, and the mechanical switching frequency tops out at 100 operations per hour at 230 V through 690 V. Terminals accept solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². Stranded: 2x (1 to 2.5 mm²) or 2x (2.5 to 10 mm²). A single 10 mm² conductor fits at 40 °C; two 10 mm² at 60 °C. The 45 mm width and 135 mm height fit standard DIN-rail spacing; depth is 155 mm.","metaTitle":"Siemens 3RT2626-1AB05 SIRIUS Capacitor Contactor, 24 VAC, S0","metaDescription":"Siemens 3RT2626-1AB05 SIRIUS capacitor contactor, S0 frame, 24 VAC coil, screw terminals.
