The Size S0 frame (85 mm high, 60 mm wide, 97 mm deep) is the mid-range footprint in the SIRIUS contactor family — bigger than S00, smaller than S2. That 97 mm depth means it'll clear most 120 mm deep enclosures, but check your gland plate clearance if you're running wires behind the rail. The coil draws 0.25 A at 50 Hz and 0.28 A at 60 Hz — not a heavy pull, but if you're powering multiple contactors from a single 24 VDC supply (through a converter), those 60 Hz inrush numbers add up. The auxiliary switch is built in (yes, it comes with one), and the main contacts accept solid or stranded wire: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) for the control circuit, and 1 to 10 mm² stranded for the power circuit. For a 24 VDC load, it's rated 10 A; at 230 VAC it's 10 A; at 400 VAC it drops to 3 A. That's the thermal current, not the motor-breaking current, so match it to your load type. The arcing time is listed at 10 to 10 ms — tight and consistent, which helps with coordination in a motor control center.","metaTitle":"Siemens 3RT2327-1AL20 SIRIUS Contactor, Size S0, 230 VAC Coi","metaDescription":"Siemens 3RT2327-1AL20 SIRIUS contactor, Size S0, 230 VAC 50/60 Hz coil.
