This Siemens power contactor is a 3-pole contactor designed for AC-3 applications, capable of handling 80 A and controlling motors up to 37 kW at 400 V ac.
The contactor is suitable for general-purpose switching but for high-frequency switching applications, it's important to refer to the datasheet for the specific operating current and mechanical endurance ratings.
The control voltage for this contactor is 24 V DC, which is the standard for the coil operation.
The exact dimensions can be found in the datasheet, but it is a Size S3 contactor, which is a standard size within the Siemens contactor range.
While the contactor has a robust design, suitability for marine environments would depend on specific certifications and approvals. Please check the product approvals section in the datasheet for detailed information.
The insulation voltage rating of this contactor is 1000 V, which is the nominal value for safe operation.
The mechanical service life of the contactor is typically around 10 million switching cycles, indicating its durability and longevity in applications.
This contactor is equipped with screw terminals, which are designed for secure and reliable wire connections.
The operating temperature range for this contactor is from -25 to +60 degrees Celsius, ensuring reliable operation in a wide range of environmental conditions.
For more detailed technical information, including certifications, electrical endurance, and switching frequency, please refer to the manufacturer's datasheet and product documentation.
