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.","metaTitle":"Siemens 3RT5066-6AV36 SIRIUS S10 Power Contactor, 197 kW at","metaDescription":"Siemens 3RT5066-6AV36 SIRIUS S10 power contactor, 197 kW at 400 V 60°C, 1000 V insulation, screw terminals.

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."},{"question":"Will 3RT5066-6AV36 drop into a panel specified around 3RT5066-6AP36?","answer":"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."},{"question":"What compliance documentation does Siemens provide for 3RT5066-6AV36?","answer":"RoHS compliance dated March 1, 2017.
