## Summary description

The Siemens 3RT2936-1CD00 is a surge suppressor module equipped with an RC element, designed for reliable protection of contactors. It operates within a voltage range of 127-240V AC and 150-250V DC. This component effectively minimizes voltage spikes, ensuring stable operation and extending the service life of industrial switching equipment in various electrical control systems.

## Long description

The Siemens 3RT2936-1CD00 is a high-quality surge suppressor module featuring an integrated RC element, specifically engineered to protect contactors from damaging voltage spikes. By effectively dampening transient overvoltages, this component ensures the reliable and stable operation of industrial switching equipment, ultimately contributing to a longer service life for your electrical control systems.
Advantages
This surge suppressor provides essential protection for sensitive electronic components within control circuits by limiting voltage peaks that occur during the switching of inductive loads. Its robust design ensures seamless integration with compatible contactors, maintaining consistent performance even in demanding industrial environments. By reducing electrical noise and preventing premature wear of contactor coils, it helps maintain the integrity of the entire control system.
Suitable for
Industrial automation control systems
Protection of contactor coils in switching applications
Electrical panels requiring transient voltage suppression
Systems operating within 127-240V AC or 150-250V DC ranges
When it may not be suitable
This module is not intended for use in circuits exceeding the specified voltage range of 127-240V AC or 150-250V DC. It is also not suitable for applications requiring different suppression technologies, such as varistors or diodes, if the specific electrical characteristics of the load demand a different suppression profile.
Key specifications
Voltage range: 127-240V AC and 150-250V DC
Suppression type: RC element
Compatibility: Designed for specific Siemens contactors
Function: Transient voltage spike suppression
How to use
The surge suppressor is designed for direct mounting onto the contactor. Ensure the power supply to the control circuit is disconnected before installation. Align the module with the designated interface on the contactor and press firmly until it clicks into place. Verify that the electrical connections are secure and that the voltage ratings of the suppressor match your control circuit requirements before restoring power.
What to consider before purchase
Verify the compatibility of the module with your specific contactor series
Ensure the control circuit voltage falls within the 127-240V AC or 150-250V DC range
Confirm that the space available in the control cabinet allows for the addition of the suppressor module
Usage recommendations
Always perform a functional test of the control circuit after installation to ensure the suppressor is correctly seated and operating as intended. Regularly inspect the module during scheduled maintenance to ensure no physical damage has occurred.
