The headline motor ratings at 60 °C are the ones that matter for a panel build: 13.3 kW at 230 V, 23 kW at 400 V, and 40 kW at 690 V. These are not the idealised 40 °C numbers — they reflect the actual current-carrying capacity when the contactor is inside an enclosure with other heat sources. Mechanical endurance is rated at 10,000,000 operating cycles typical, with AC-3 electrical life at 750 cycles per hour maximum. For high-duty applications like frequent reversing or inching, the AC-4 maximum drops to 250 cycles per hour — that's the figure to size against if your load profile includes plugging or jogging. The coil draws 6 A at 24 V rated value, 1 A at 110 V, and 0.3 A at 220 V. These are the inrush figures for sizing control transformers and power supplies — the holding current will be lower, but the pick-up is what stresses the circuit. Terminal capacity for the main circuit accepts 2 x (0.5 to 1.5 mm²) or 2 x (0.75 to 2.5 mm²) solid or stranded wire. Minimum permissible cross-section at both 40 °C and 60 °C is 10 mm² — that's the smallest wire that carries the full rated current without exceeding temperature limits.","metaTitle":"Siemens 3RT6026-1AL20 SIRIUS Power Contactor, S0, 23 kW at 4","metaDescription":"Siemens 3RT6026-1AL20 SIRIUS power contactor, size S0.
