The DC magnet coil draws 0.7 W during closing and holds at 0.29 W — low enough for direct PLC output drive without an interposing relay in most cases. The control circuit terminals are screw-type, same as the main circuit, keeping your wiring tooling consistent across the panel. Rated surge voltage resistance is 6 kV, which aligns with IEC 60947-1 coordination for industrial environments. ## Environmental and protection ratings Operating temperature range is -10 to +55 °C, storage from -25 to +70 °C.","metaTitle":"Siemens 3RT7046-1AH20 SIRIUS Contactor, 3-Pole, 690V AC-3, S","metaDescription":"Siemens 3RT7046-1AH20 SIRIUS S3 contactor, 3-pole, 690V AC-3 max, screw terminals, IP20 front.
