An auxiliary switch is included, configurable as 1 NO + 1 NC (the 18...8 notation means 18 terminals for the NO block, 8 for the NC). The auxiliary contacts carry 10 A at 24 V, 10 A at 230 V, and 3 A at 400 V — enough for pilot duty on PLC inputs or relay coils. ## Wiring & Integration Main circuit terminals accept solid conductors 2x (0.5...2.5 mm²) or stranded 1...10 mm². The magnet coil uses spring-type terminals for fast wiring without re-torquing. Dimensions are 60 mm wide, 102 mm high, 97 mm deep. Operating time is 4...16 ms AC; arcing time is 10...10 ms. The size S0 frame means it occupies the same footprint as other S0 accessories like auxiliary contact blocks and surge suppressors. This part carries a current lifecycle stage from the manufacturer, meaning it remains in the active catalog for new designs and replacement orders. The SIRIUS series is widely stocked, so RFQ turnaround is typically fast.","metaTitle":"Siemens 3RT2327-2AC20 SIRIUS Contactor, Size S0, AC Coil 24V","metaDescription":"Siemens 3RT2327-2AC20 SIRIUS contactor, size S0, AC coil 24V 50/60Hz.
