Product details

SIRIUS power contactor, size S3 — 38.2 kW at 690 V

The Siemens 3RT1446-1BD40 is a SIRIUS power contactor in frame size S3, rated for motor switching up to 38.2 kW at 690 V AC-3 and 29.9 kW at 500 V AC-3. Insulation voltage is 1000 V, so it handles 690 V line-to-line with margin.

Main circuit terminals are screw-type, accepting solid or stranded conductors: 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), max. 2x (0.75…4 mm²) for control wiring; 2x (2.5…16 mm²) and 2x (10…50 mm²) stranded for power. The IP20 rating on the front (with cover/box terminal) means finger-safe touch protection in the panel; the terminal itself is IP00, so live parts are exposed when the cover is off.
