Capacitor switching duty — what the ratings mean
The 3RT2627-1AK65: This is a dedicated capacitor contactor from the SIRIUS series, not a general-purpose contactor with a derated coil. These numbers reflect the inrush current and restrike suppression needed when switching power-factor-correction capacitors — a standard general-purpose contactor would weld its contacts on the same duty. The coil is 110 V AC at 50 Hz (120 V at 60 Hz) with screw-type terminals. Coil draw is not listed in this excerpt, but the operating range spans -25 to +60 °C ambient, with storage down to -55 °C.
Panel fit and wiring capacity
That flexibility helps when the contactor sits behind a capacitor bank's busbars. The 10 mm² stranded capacity covers the main power feed for the capacitor bank; the smaller terminals handle the control wiring. No auxiliary contact block is attachable (0 auxiliary contacts listed), so if you need a feedback signal to the PLC, order a separate auxiliary contactor or a contactor with an integrated block.
Lifecycle status is current production — this is an active Siemens catalog part, not a legacy or phase-out line. That means factory support, no last-time-buy scramble, and consistent lead times through distribution. The 3RT2627 series is a standard building block in power-factor-correction panels across Europe and Asia; availability is typically steady. For BOM-quantity pricing and lead time, submit an RFQ. This part is sourced through authorized Siemens distribution channels; stock is confirmed at quote time.
