The Siemens 3RV2901 Series Auxiliary Switch is a compact and reliable component designed for seamless integration with circuit breakers of sizes S00 and S0. This auxiliary switch, featuring a transverse design, is engineered to facilitate the monitoring and control of circuit breaker status within an electrical distribution system.
Crafted with precision, the switch boasts a robust screw mount installation method, ensuring a secure and stable connection. Its dimensions of 45 x 17 x 12 mm make it an ideal choice for applications where space is at a premium. The switch operates efficiently at a voltage of 230 V and includes 2 normally open (NO) contacts, which are essential for various control circuit configurations.
The auxiliary switch's electrical connection is designed for screw-type terminals, accommodating a range of conductor cross-sections, both solid and finely stranded, with or without conductor end processing. This versatility ensures compatibility with diverse wiring practices and simplifies installation.
With a protection class of IP20 on the front, the switch is safeguarded against solid objects larger than 12.5 mm, providing a degree of protection for the internal components. It operates reliably within an ambient temperature range of -20 to +60 degrees Celsius, making it suitable for a wide array of operating environments.
The Siemens 3RV2901 Series Auxiliary Switch is a testament to the brand's commitment to quality, reliability, and innovation, making it a valuable addition to any electrical distribution system.

What is the function of an auxiliary switch like the Siemens 3RV2901 Series?
An auxiliary switch is used to provide additional switching operations, typically for signalling, interlocking, or control circuit purposes. It can be used to indicate the status of a circuit breaker, such as whether it's open or closed, and to control auxiliary circuits that are separate from the main circuit.
Can this auxiliary switch be used with any size of circuit breaker?
The Siemens 3RV2901 Series auxiliary switch is designed to be compatible with circuit breakers of sizes S00, S0, S2, and S3. It's important to match the auxiliary switch to the correct size of the circuit breaker for proper operation.
What type of terminals does this auxiliary switch have for connection?
This auxiliary switch comes with screw-type terminals, which are used for secure and reliable electrical connections to the auxiliary and control current circuits.
What is the protection class of this auxiliary switch?
The protection class for the front of this auxiliary switch is IP20, which means it is protected against solid objects larger than 12.5mm but not against water.
What are the ambient temperature limits for operating this auxiliary switch?
The auxiliary switch can operate within an ambient temperature range of -20°C to +60°C and can be stored in temperatures ranging from -50°C to +80°C.
How many normally open (NO) contacts does this auxiliary switch have?
