That means it pulls in reliably even if the control transformer sags under load — a common headache in older panels where the AC bus droops during simultaneous pickup. ## Auxiliary contact ratings across the voltage band This covers most control circuit voltages you'll find in a panel — 24 V for PLC inputs, 110–230 V for legacy relay logic, and 400 V for direct switching of small loads without an intermediate relay. The maximum switching rate is 180 cycles per hour across the full voltage range from 230 V to 690 V. That's one operation every 20 seconds — fine for capacitor bank stepping or infrequent load switching, but not for high-speed applications like a rapid cycling heater or a test stand. ## Mounting and wiring flexibility At 40 °C ambient, the recommended conductor cross-section is 1×4 mm² or 2×2.5 mm²; at 60 °C it's 2×4 mm². That derating curve matters if the contactor sits near other heat sources inside a sealed cabinet — you'll need to upsize the wire or keep the ambient down. Sourced through authorized distribution channels. No stock-holding claim here — it's a quoted-to-order item, which keeps your cost in line with the market.","metaTitle":"Siemens 3RT2617-1AP03 SIRIUS Capacitor Contactor, S00, 45 mm","metaDescription":"Siemens 3RT2617-1AP03 SIRIUS capacitor contactor, size S00, 45 mm wide, screw terminals.
