It handles 13.3 kW at 230 V and 40 kW at 690 V under the same AC-3 duty (cite:,). The AC-3 maximum switching frequency is 750 cycles per hour, with a mechanical life of 10 million operations typical (cite:,). For resistive loads (AC-1) it can switch up to 1,000 cycles per hour (cite:). Width is 45 mm, depth 107 mm, height 85 mm — fits a standard S0 footprint (cite:,). Side-by-side mounting is allowed (cite:). ## Terminals and wiring Main current circuit and auxiliary/control circuit both use screw-type terminals (cite:,). Accepts 2x (0.5...1.5 mm²) solid or stranded, or 2x (0.75...2.5 mm²) (cite:). For AWG: 2x (16...12) or 2x (14...8) (cite:). Minimum cross-section at 40 °C and 60 °C is 10 mm² (cite:,).","metaTitle":"Siemens 3RT6026-1BM40 SIRIUS Power Contactor, 23 kW at 400 V","metaDescription":"Siemens 3RT6026-1BM40 SIRIUS power contactor, size S0, 23 kW at 400 V AC-3.
