Siemens SIRIUS 3RT2035-1NB34-ZX95 — Size S2 Power Contactor, 20-33 V Coil
The Siemens SIRIUS 3RT2035-1NB34-ZX95 is a size S2 power contactor with a screw-type coil terminal block rated for 20 to 33 V. It snaps onto a 35 mm DIN rail per DIN EN 60715 and measures 55 mm wide by 174 mm deep by 114 mm tall — that's another SKU that fits a standard panel footprint without surprises. The coil draws 2 VA at both 50 Hz and 60 Hz, with an inrush peak of 3 A. Operating temperature range is -25 to +60 °C, storage from -55 to +80 °C. The mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward or backward — handy when you're squeezing it into a crowded backplane.
Panel Fit and Wiring
Wire termination accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded conductors. Clearance spacing: 10 mm upward, 10 mm forward, 10 mm downward, 6 mm at the side. The main contact configuration is 18 normally open contacts, 1 normally closed — that's the standard S2 contactor layout for motor switching. No auxiliary switch block is fitted as standard — the -ZX95 suffix indicates a special variant, so verify your auxiliary contact needs separately. The screw-type coil terminals are straightforward for panel wiring; no special tooling required beyond a standard screwdriver.
