Product information

Description

The Siemens 3RV2901-1A auxiliary switch is a precision-engineered component designed for seamless integration with S00 and S0 size circuit breakers. This side-mounted device provides essential feedback on the switching status of the main circuit breaker, facilitating reliable monitoring and control within industrial electrical installations. With its robust construction and standardized design, it ensures consistent performance in demanding electrical distribution environments.

Advantages

This auxiliary switch offers high reliability and ease of installation due to its side-mounting configuration, which saves space within control cabinets. The inclusion of both normally open and normally closed contacts provides versatile signaling options for various automation and safety circuits. Its durable design and screw terminal connections ensure a secure electrical contact, minimizing the risk of signal loss or maintenance requirements over the long term.

Suitable for

  • Industrial control panels
  • Electrical distribution systems
  • Automation and monitoring of circuit breaker status
  • Safety-critical signaling applications

This component may not be suitable for applications requiring high-power switching, as it is designed specifically for signal-level feedback. It is also not intended for use with circuit breakers outside of the specified S00 and S0 size ranges or non-compatible series.

Key specifications

  • Contact configuration: 1 NO + 1 NC
  • Mounting type: Side-mounted
  • Connection type: Screw terminals
  • Protection rating: IP20
  • Rated current: 10 A
  • Compatibility: S00 and S0 size circuit breakers
  • Weight: 0.049 kg
  • Colour: Black

To install the auxiliary switch, ensure the main circuit breaker is disconnected from the power supply. Align the switch with the side of the circuit breaker housing and snap it into place according to the manufacturer's mechanical interface. Once secured, connect the control wires to the designated screw terminals, ensuring that the wire gauge is appropriate for the terminal capacity. Verify the connection by testing the signaling function before putting the system into full operation.

What to consider before purchase

  • Verify compatibility with your specific circuit breaker size (S00 or S0)
  • Ensure the control voltage and current requirements match your system design
  • Check available space on the side of the breaker within your enclosure
Usage recommendations: Always perform a functional test of the auxiliary switch after installation to confirm that the signaling contacts correctly reflect the state of the circuit breaker. Ensure all screw terminals are tightened to the specified torque to prevent loose connections.
