Product Positioning

The 3RV2901-2A is a side-mounted auxiliary switch specifically designed for Siemens SIRIUS 3RV2 series circuit breakers. It provides 1 NO + 1 NC contacts and uses spring-loaded terminal connections. It has the same function as the crimp-lug version 3RV2901-4A, but the wiring method is different.

Core Product Advantages and Features

1NO+1NC contact configuration

It provides a set of normally open and a set of normally closed contacts, which can be used for status display or safety interlock circuit design.

Spring-loaded terminal connection

Using spring clip terminals, wires can be crimped without tools, significantly reducing wiring installation time.

Side mounting method

It can be side-mounted on the 3RV2 S00/S0 series circuit breakers, with the same installation position as the 3RV2901-4A.

Lightweight design

Each unit weighs only about 0.034 kg, and its installation on the panel does not add any extra weight.
