## Summary description

The Siemens SIRIUS 3RT2926-1BD00 is a high-quality varistor surge suppressor designed for use with SIRIUS contactors. It provides effective protection against voltage peaks in control circuits, supporting an operating voltage range of 127-240V AC and 150-250V DC. This accessory ensures reliable operation and extends the service life of switching components in industrial automation systems.

## Long description

The Siemens SIRIUS 3RT2926-1BD00 is a high-quality varistor surge suppressor engineered to protect industrial control circuits from damaging voltage spikes. Designed specifically for integration with SIRIUS 3RT2.2 contactors, this accessory ensures the longevity and reliability of your switching components by effectively clamping transient overvoltages. Its compact design allows for seamless installation directly into the existing slots of compatible contactors, maintaining the original footprint of your control cabinet.
Advantages
This surge suppressor offers a robust solution for maintaining electrical stability in automated systems. By mitigating voltage peaks, it prevents premature wear on contactor coils and sensitive electronic control equipment. The device is designed for quick and tool-free installation, fitting perfectly into the designated slots of the contactor without increasing the overall dimensions of the assembly. This integration supports the modular nature of the SIRIUS system, ensuring that your industrial setup remains efficient, organized, and protected against electrical disturbances.
Suitable for
Industrial automation control panels
Motor control centers
Switchgear assemblies
Protection of PLC outputs and relay coils
Systems requiring transient voltage suppression for 127-240V AC or 150-250V DC circuits
When it may not be suitable
This device is specifically calibrated for use with Siemens SIRIUS 3RT2.2 contactors and may not be compatible with contactors from other series or manufacturers. It is not intended for use in circuits exceeding the specified voltage ranges of 127-240V AC or 150-250V DC.
Key specifications
Operating voltage range: 127-240V AC (50/60 Hz) and 150-250V DC
Compatibility: Designed for SIRIUS 3RT2.2 contactors
Technology: Varistor-based surge suppression
Mounting: Plug-in design for integrated contactor slots
How to use
Installation is straightforward due to the modular design of the SIRIUS system. Ensure that the power supply to the contactor is disconnected before beginning the installation. Locate the designated slot on the front or side of the 3RT2.2 contactor. Insert the varistor surge suppressor firmly into the slot until it clicks into place. Once installed, the device operates automatically, providing continuous protection against voltage surges during the switching cycles of the contactor.
What to consider before purchase
Verify that your contactor model is part of the SIRIUS 3RT2.2 series.
Confirm that your control circuit voltage falls within the 127-240V AC or 150-250V DC range.
Ensure there is sufficient space in your control cabinet for the contactor assembly.
Usage recommendations
Always verify the voltage specifications of your control circuit before installation to ensure compatibility. Regularly inspect the surge suppressor during routine maintenance to ensure it remains securely seated in the contactor slot.
