Product details

Active production — quoted to order

The 3RT2617-1AB03: Sourced through authorized distribution channels against the BOM quantity.

Switching capability across the AC voltage range

The contactor is designed specifically for capacitor bank switching, not general motor starting — the inrush handling and arc suppression are tuned for capacitive loads. Maximum switching rate is 180 operations per hour across all voltage ratings from 230 V to 690 V AC.

DIN rail footprint and panel fit

Size S00 frame, 45 mm wide by 125 mm tall by 120 mm deep. At 40 °C ambient, single 4 mm² or 2x 2.5 mm² is permitted; at 60 °C, 2x 4 mm². The coil terminals are screw-type as well.

Temperature range and arc timing

Arc duration is 10...15 ms with an AC arcing time of 4...15 ms — this matters when coordinating upstream short-circuit protection devices, as the let-through energy during capacitor switching can differ from resistive or motor loads.

Frequently asked questions

What is the 3RT2617-1AB03 used for?

It is a SIRIUS capacitor contactor designed for switching capacitor banks in power factor correction applications. Not intended for general motor starting — the arc-quenching and inrush characteristics are optimized for capacitive loads.
