Product Positioning

The 3RV2917-1A is a three-phase busbar of the Siemens SIRIUS 3RV2 incoming line system. It adopts a left-side incoming line design and can allow two sets of S00/S0 frame circuit breakers to share the same power supply line. It is a counterpart to the 3RV2917-1E with left and right incoming lines.

Core Product Advantages and Features

Left-side cable entry design

The power supply is introduced from the left side, which complements the 1E right-inlet model and can be flexibly selected according to the control panel configuration.

Two sets of circuit breakers share the power supply.

A single busbar can simultaneously supply power to two sets of S00/S0 frame circuit breakers.

Spring-loaded terminal wiring

The main circuit uses spring-loaded terminal connections, eliminating the need for screws and speeding up panel wiring.

RoHS compliant

The product design complies with the RoHS environmental directive and is suitable for projects with environmental regulations.
