3RT1075-6AM36

The 3RT1075-6AM36, part of Siemens' SIRIUS series, is a power contactor engineered for superior performance in robust applications. It supports a main circuit operation with a voltage rating of 1,000 Volts AC and features a configuration of three poles. This model incorporates three normally open (NO) contacts, enabling effective control within electrical circuits.

The operating current of this contactor ranges from 180 Amperes to 430 Amperes, making it suitable for substantial power handling. It achieves rated operating power between 132 and 400 kilowatts. Furthermore, this contactor is designed to operate within ambient temperatures, spanning from -25 to 60°C, in environments that do not condense moisture. For extreme conditions, it can tolerate storage temperatures between -55 and 80°C.

Its mechanical service life is notably extensive, rated at 5 to 10 million switching cycles, which adds to its long-term reliability. The unit also boasts a surge voltage resistance of 6 to 8 kilovolts, providing an extra layer of protection against electrical disturbances. Electrical connections are facilitated via screw-type terminals and connection bars, ensuring secure and stable connectivity.

The auxiliary contacts include two normally open (NO) and two normally closed (NC) contacts, enhancing its versatility in various applications. The power loss during operation is recorded at a range of 10 to 105 Watts, indicating efficient energy management. Overall, the contactor size is classified as S12, positioning it compactly for installation in multiple environments.
