Product details

SIRIUS S0 power contactor — 23 kW motor switching at 400 V

Snap-on mounting onto 35 mm rail per DIN EN 50022, with ±180° rotation on vertical surfaces and ±22.5° tilt allowance — useful when gland-plate clearance is tight. Rated for AC-3 duty up to 690 V, the contactor delivers 23 kW at 400 V 60°C and 40 kW at 690 V 60°C — covering most 400 V three-phase motor loads up to 30 kW frame size. The 10 A rated operational current at 230 V (AC-1) handles resistive heater banks or lighting circuits. Insulation voltage rated 690 V, pollution degree 3, so it's suited for industrial environments without additional derating for moderate contamination.

Side-by-side mounting permitted (zero gap), so you can pack multiple contactors on a single rail without derating for heat buildup. Screw terminals accept 2x (0.5…2.5 mm²) solid/stranded for control wiring, and 2x (16…12 AWG) or 2x (14…8 AWG) for main power — strip length and ferrule sizing follow standard panel practice. Operating temperature range -25…+60 °C; storage range -55…+80 °C.

Frequently asked questions

What is the closest functional second-source for 3RT6023-1AB00?

The 3RT6024-1AP00 is a higher-current sibling in the same S0 frame — it shares the same 45 mm width, DIN-rail mounting, and screw-terminal layout, but carries a higher AC-3 rating. It will drop into the same panel footprint without rewiring, though the coil voltage and auxiliary contact configuration differ — verify those against your BOM before substituting.

What compliance documentation does Siemens provide for 3RT6023-1AB00?

The contactor is RoHS compliant with a substance prohibition date of 05/01/2012. Siemens provides declarations of conformity and material declarations through their Industry Mall. For UL/CSA certification, check the specific variant suffix — the -1AB00 base model typically carries CE and UKCA markings for European markets.

Where can I buy 3RT6023-1AB00?
