Product details

SIRIUS S10 power contactor — 3RT5066-6AV36

Siemens 3RT5066-6AV36 is a SIRIUS S10 power contactor rated for motor switching at 197 kW at 400 V 60°C and 340 kW at 690 V 60°C. Insulation voltage is 1000 V, so it handles 690 V line-to-line with headroom for transient spikes common on industrial motor circuits. Coil suppression is built in with a varistor — no external snubber needed for inductive load switching. Screw-type terminals on the main circuit accept 185 mm² at 60°C or AWG 2/0 to 500 kcmil. That's a heavy lug — sized for the full 197 kW motor feed without needing a separate terminal block.

Mounting and mechanical

Fastening is screw fixing with a vertical mounting surface. Dimensions: 210 mm high, 145 mm wide, 202 mm deep. That S10 frame is a known footprint; if you're replacing a 3RT5065 or 3RT5066 in an existing panel, check the depth clearance — 202 mm is deeper than the 3RT5065's roughly 180 mm.

Frequently asked questions

What is the closest functional second-source to 3RT5066-6AV36?

The 3RT5066-6AP36 is the same S10 frame with the same 197 kW at 400 V rating, but with a different coil voltage or auxiliary configuration. The 3RT5065-6AP36 and 3RT5065-6AR36 are the next frame down (S6/S7) with lower power ratings — they won't carry the same motor load. Check the coil code before swapping; the -6AV36 suffix indicates a specific coil variant.

Will 3RT5066-6AV36 drop into a panel specified around 3RT5066-6AP36?

Mechanically yes — same S10 frame, same screw fixing pattern, same 210 x 145 x 202 mm envelope. The electrical fit depends on the coil voltage matching. If the -6AP36 had a different coil, you'd need to verify the control circuit voltage before substitution.

What compliance documentation does Siemens provide for 3RT5066-6AV36?

RoHS compliance dated March 1, 2017. Pollution degree 3 per IEC 60947-1. The SIRIUS series carries UL/CSA/CE certifications as standard, though specific cert numbers are not in this listing.
