For DC switching, the 24 V rated value is 10 A, 48 V is 2 A, 60 V is 6 A, 110 V is 1 A, 125 V is 0.9 A, 220 V is 0.3 A, 500 V is 2 A, and 690 V is 1 A. These are the make/break limits for resistive loads — inductive loads will need derating per the application note. ## Coil data and operating conditions The magnet coil uses screw-type terminals and is rated for AC supply. At 50 Hz the coil power draw is 0.38 (likely VA or W — the unit is implied by the field). The arcing time across the main contacts is 10 to 21 ms at AC, with a total arcing time of 10 to 20 ms. The mechanical endurance is 10 million operating cycles typical. ## Wiring and short-circuit protection Main circuit wiring accepts stranded conductors from 6 to 70 mm². For short-circuit protection, the required fuse is type gB rated 200 A at 750 V with a 25 kA breaking capacity. This sets the SCCR for the contactor branch in the panel.","metaTitle":"Siemens 3RT2346-1AP00-4AA0 SIRIUS Contactor, Size S3, 70 mm","metaDescription":"Siemens 3RT2346-1AP00-4AA0 SIRIUS contactor, Size S3, 70 mm width, 152 mm depth.
