Mechanical life is rated at 10 000 000 cycles typical, and the maximum switching rate at AC-1 is 650 operations per hour. Both the main current circuit and the auxiliary/control circuit use screw-type terminals. The main contacts accept solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and up to 2x (0.75 to 4 mm²). For AWG cables, the range is 7 to 1/0. Minimum permissible conductor sizes are 50 mm² at 40 °C and 35 mm² at 60 °C — derate for higher ambient temperatures. ## Switching Performance and Duty Ratings At 230 V and 60 °C ambient, it handles 50 kW; at 690 V and 60 °C, it handles 148 kW — note these are at elevated temperature, so the coil hold and contact life are derated accordingly. For DC switching, the contactor is rated 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V.","metaTitle":"Siemens 3RT1446-6BB46-ZM96 SIRIUS Power Contactor, Size S3,","metaDescription":"Siemens SIRIUS 3RT1446-6BB46-ZM96 power contactor, Size S3, 24 VDC coil, rated 29.9 kW at 500 V and 38.2 kW at 690 V.
