It switches motor loads at 23 kW on a 400 V line at 60 °C ambient, or 40 kW at 690 V at the same temperature — figures that govern the real thermal capacity in a closed panel, not the open-air headline. The 45 mm width leaves room for a full motor starter assembly in a standard enclosure without crowding the gland plate. RoHS compliance is documented with a substance prohibitance date of 05/01/2012, aligning with the EU RoHS recast deadline. The SIRIUS series carries CE marking as standard; UL and CSA listings are typical for the family but should be verified per specific catalog number. ## Integration into a panel Screw-type terminals on the main current circuit accept 2x (0.5…1.5 mm²) or 2x (0.75…2.5 mm²) solid or stranded conductors. Minimum permissible cross-section at both 40 °C and 60 °C is 10 mm², so the same wire gauge works across the full operating range. Depth of 97 mm fits standard 120 mm deep enclosures with clearance for wiring. Mechanical endurance of 10 million operations typical; electrical switching rates at AC-3 maximum 750 cycles/hour, AC-4 maximum 250 cycles/hour. For high-duty-cycle applications like conveyor indexing or press control, the AC-4 limit is the binding constraint.","metaTitle":"Siemens 3RT6026-1AN20 SIRIUS Power Contactor, S0, 23 kW at 4","metaDescription":"Siemens 3RT6026-1AN20 SIRIUS power contactor, S0 size, 23 kW at 400 V 60°C, AC-3 rated 690 V max, screw terminals, DIN rail mount.
