SIRIUS S00 Power Contactor — 3RT1517-1AK60
Its screw-type terminals on both main and auxiliary circuits accept 2x (0.5...1.5 mm²) solid or stranded, up to 2x (0.75...4 mm²) max, with AWG equivalents 2x (20...16) and 1x 12 for the main contacts. The S00 frame keeps the footprint compact at 45 mm wide, 57.5 mm tall, and 72 mm deep — fits standard panel layouts without oversizing the enclosure.
Contact Ratings and Switching Capacity
Auxiliary contacts are rated 12 A continuous per NO and per NC contact. Switching capacity varies by voltage: 10 A at 24 V, 6 A at 230 V AC, 3 A at 400 V, and 0.8 A at 440 V. For DC loads, the contactor handles 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. These ratings cover the typical control-circuit voltages found in mixed AC/DC panels — no separate DC-rated auxiliary block needed for most signal-level switching. Short-circuit protection requires a 20 A gL/gG fuse.
With side-by-side mounting allowed, multiple contactors pack tightly in a row without derating. The screw terminals accept ferruled stranded or solid wire; strip length for the main circuit terminals is not specified here, but 8–10 mm is standard for this terminal class. Coil draw is 5.1 VA at 50 Hz and 0.27 A at 60 Hz — factor into the control transformer sizing if multiple contactors pull in simultaneously. For safety circuits requiring fast break, verify the total break time meets your PL/SIL target — the contactor alone is one element in the chain. Ambient storage covers -55 to +80 °C; operating ambient is not listed here but SIRIUS S00 contactors typically range -25 to +60 °C.
