The S3 frame size (140 mm height, 70 mm width, 152 mm depth) occupies a defined footprint on the DIN rail, so panel fill-factor planning is straightforward. ## Auxiliary Contacts and Switching Capability This contactor includes an auxiliary switch block, which is the built-in set of NO/NC contacts for feedback or interlocking. The auxiliary contacts are rated across a voltage ladder: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, down to 0.1 A at 600 V. These are the current-carrying limits for the auxiliary circuit — useful when you need to know whether the contactor's own aux contacts can handle the pilot load without an interposing relay. The main power circuit accepts stranded conductors from 6 to 70 mm², which covers most motor branch-circuit wiring up to the S3 frame's typical rating. The auxiliary terminals accept solid or stranded wire in two ranges: 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²). Arcing time is 10 to 20 ms, and the AC operating time (pick-up/drop-out) is 10 to 21 ms. These are the minimum air gaps to maintain around the contactor for heat dissipation and arc containment.","metaTitle":"Siemens 3RT2446-1AP60 SIRIUS Contactor, 220-240 VAC Coil","metaDescription":"Siemens 3RT2446-1AP60 SIRIUS contactor, 220 VAC at 50 Hz / 240 VAC at 60 Hz coil, S3 frame size.
