## Summary description

The Siemens 3RT2926-1CB00 is an RC surge suppressor designed for SIRIUS size S0 contactors. It operates within a voltage range of 24-48V AC and 24-70V DC. Featuring an integrated LED indicator, this accessory effectively suppresses voltage peaks in the control circuit, ensuring reliable operation and protecting sensitive electronic components in industrial automation systems.

## Long description

The Siemens SIRIUS RC surge suppressor is a specialized accessory designed to protect control circuits by mitigating voltage peaks. Engineered specifically for SIRIUS size S0 contactors, this component ensures the longevity and reliability of industrial automation systems by preventing electrical interference that can damage sensitive electronic equipment.
Advantages
This surge suppressor offers a seamless integration process due to its compact design that fits directly into the existing slot of the contactor without increasing its external dimensions. The inclusion of an integrated LED indicator provides immediate visual feedback regarding the status of the control circuit, allowing for faster diagnostics and maintenance. By effectively suppressing transient voltages, it enhances the overall stability of the electrical system and reduces the risk of operational downtime.
Suitable for
Industrial automation control panels
Motor starter assemblies using SIRIUS S0 contactors
Systems requiring protection against voltage spikes in control circuits
Environments where sensitive electronic components are integrated with electromechanical switching devices
This device may not be suitable for applications operating outside the specified voltage range of 24-48V AC or 24-70V DC. It is also not intended for use with contactors outside the SIRIUS S0 size category, as the physical mounting interface is specifically engineered for that series.
Key specifications
Voltage range: 24-48V AC (50/60 Hz) and 24-70V DC
Compatibility: SIRIUS size S0 contactors
Integrated feature: LED status indicator
Technology: RC (Resistor-Capacitor) surge suppression
Installation is straightforward and requires no complex tools. The suppressor is designed to be inserted into the designated slot on the front of the compatible contactor. Once inserted, it functions automatically to dampen voltage surges during the switching process of the contactor coil.
What to consider before purchase
Verify the coil voltage of your existing contactor matches the suppressor specifications
Ensure the contactor is a SIRIUS size S0 model
Check available space in the control cabinet to confirm the slot is accessible
Usage recommendations: Always ensure the power supply is disconnected before installing or removing the surge suppressor to prevent electrical hazards. Regularly inspect the LED indicator during routine maintenance to confirm the suppressor is functioning correctly.
