The coil is AC-operated, rated 220 V at 50 Hz and 240 V at 60 Hz, with screw-type terminals for the magnet coil — a detail that matters when wiring the control circuit because you land the coil leads directly under a screw clamp, not a quick-connect tab. 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.
