The 45 mm width and 107 mm depth fit the S0 footprint, and screw-and-snap-on mounting onto 35 mm DIN rail per DIN EN 50022 means it clips into a standard panel rail without extra brackets. ## Motor power ratings and switching frequency — sizing the contactor for the duty At 60 °C ambient, the 3RT6023-1BB40 delivers 13.3 kW at 230 V, 23 kW at 400 V, and 40 kW at 690 V — these are the AC-3 motor-switching ratings that govern real-world sizing, not the AC-1 resistive numbers. Maximum switching frequency is 1 000 cycles per hour for AC-3 and AC-3e duty, dropping to 300 cycles per hour for AC-4 (plugging/reversing). For DC switching, the maximum is 1 500 cycles per hour. ## DIN rail mounting and wiring — panel integration notes Side-by-side mounting is permitted (no minimum air gap required for thermal derating in standard conditions). Main circuit terminals are screw-type, accepting 2x (0.5...1.5 mm²) solid/stranded or 2x (0.75...2.5 mm²), and AWG 2x (16...12) or 2x (14...8). Minimum wire size at 40 °C and 60 °C is 10 mm² for the main contacts. Auxiliary and control circuit terminals are also screw-type. An auxiliary switch can be added externally via the product extension slot. The insulation voltage rated value is 690 V, matching the AC-3e maximum. Substance prohibitance date is 05/01/2012, aligning with RoHS compliance for the EU RoHS recast. The SIRIUS brand carries CE, UL, CSA, and IEC certifications through the Siemens portfolio; specific documentation (declaration of conformity, IEC 60947-4-1 test reports) is available with the order.","metaTitle":"Siemens 3RT6023-1BB40 SIRIUS Contactor, 24 VDC, 23 kW at 400","metaDescription":"Siemens 3RT6023-1BB40 SIRIUS power contactor, 24 VDC coil, AC-3e rated 690 V max, 23 kW at 400 V 60°C.
