Product details

Rated for 113 kW at 230 V, 197 kW at 400 V, and 340 kW at 690 V — those are the AC-3 motor-duty figures that tell you what induction motor it can handle on a given line voltage.

Fastens with screw fixing, not DIN-rail snap-on. Mounting position is flexible — vertical surface, rotatable ±90°, tiltable ±22.5° front and back. Dimensions: 145 mm wide, 210 mm high, 202 mm deep. That depth matters when you're laying out a panel — 202 mm means it'll clear a standard 250 mm enclosure depth with room for wiring. Wire range on the main terminals accepts 2/0 to 500 kcmil AWG.

Switching frequency and coil data

Maximum mechanical switching rate: 2 000 cycles per hour for both AC and DC operation. For specific duty classes: AC-1 (resistive) max 750 cycles/h, AC-3 (motor start/run) max 500 cycles/h, AC-4 (plugging/inching) max 130 cycles/h. Coil rated voltage is 240–277 V at 50/60 Hz. Coil pick-up current at 24 V is 6 A, at 110 V is 1 A, at 220 V is 0.3 A, at 230 V is 6 A, at 400 V is 3 A. Those are inrush values — the holding current will be lower. The built-in varistor handles surge suppression across the coil.

Pollution degree 3 (industrial environment with conductive pollution). Mechanical endurance typical 10 million operating cycles. RoHS compliance substance prohibition date 03/01/2017 — meets current RoHS requirements.

Frequently asked questions

Where can I buy 3RT5066-6AU36 and get a price?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

Will 3RT5066-6AU36 drop into a panel specified for 3RT5066-6AP36?

Both are SIRIUS Size S10 power contactors with the same frame dimensions (145 mm wide, 210 mm high, 202 mm deep) and screw-type terminals. The 6AP36 variant has a different coil voltage — verify your control voltage matches the 240–277 V coil on this 6AU36 before swapping.

What compliance documentation does Siemens provide for 3RT5066-6AU36?

RoHS compliant with substance prohibition date 03/01/2017. Pollution degree 3 rated. Insulation voltage 1000 V. Standard Siemens SIRIUS documentation package includes CE declaration and IEC/EN compliance.
