At 400 V and 60 °C, the contactor is rated for 13 kW motor power; at 690 V and 60 °C, that rises to 22 kW. These are the practical limits for continuous motor duty — size your load against these, not the raw current figures, because the thermal derating at elevated ambient temperature governs real-world performance. The AC-3 maximum switching frequency is 750 operations per hour, which covers most pump, fan, and conveyor cycles without exceeding the mechanical life of 30 million operations. The 73 mm depth and 57.5 mm height keep the contactor compact for DIN-rail enclosures. Side-by-side mounting is permitted, so multiple contactors can pack tightly on the rail without derating for spacing.","metaTitle":"Siemens 3RT6018-1AF01 SIRIUS Power Contactor, Size S00, 24 V","metaDescription":"Siemens 3RT6018-1AF01 SIRIUS power contactor, Size S00, 24 VDC coil, 45 mm wide, screw terminals, AC-3 switching up to 690 V.
