The 3RT2625-1AB05 handles the high peak currents without welding its main contacts, provided the capacitor bank capacitance does not exceed the manufacturer's recommended value for the S0 frame. ## Mounting and terminal details for panel integration The 1×6 mm² at 40 °C and 1×10 mm² / 2×6 mm² at 60 °C ratings give the wireman a clear derating table for the power circuit. ## Switching performance and operating limits The arcing time is a tight 10–10 ms, and the closing time at AC is 4–16 ms — consistent with the SIRIUS capacitor contactor family's fast make/break characteristic. Auxiliary contact configuration: one instantaneous contact (NO or NC depending on variant) — the 3RT2625-1AB05 ships with a single auxiliary block as standard. ## Lifecycle and sourcing for the BOM line No stock-holding claim is made; the supply posture is RFQ-grounded.","metaTitle":"Siemens 3RT2625-1AB05 SIRIUS Capacitor Contactor, S0","metaDescription":"Siemens SIRIUS 3RT2625-1AB05 capacitor contactor, size S0, 24 V AC 50 Hz coil, 6 A at 230 V.
