Product Positioning

The 3RV2901-1J is a side-mounted auxiliary switch specifically designed for Siemens SIRIUS 3RV2 series circuit breakers. It provides four sets of contacts (2NO + 2NC) and uses screw terminal connections, supporting the status feedback and interlocking requirements of multiple control circuits simultaneously.

Core Product Advantages and Features

There are a total of 4 contact groups: 2NO and 2NC.

It provides four independent contacts at a time, which can simultaneously drive indicator lights, PLC signal inputs, and safety interlock circuits.

Screw terminal connection

The screw-locked terminal wiring ensures a stable and reliable connection, making it suitable for long-term industrial power distribution environments.

Rated 690V AC, 10A

The contacts have high rated voltage and current, which can meet the application requirements of large load signal circuits.

Widely compatible models

It can be installed on various sizes of motor protection circuit breakers such as SIRIUS 3RV2 S00, S0, S2, and S3.
