Product Positioning

The Siemens SIRIUS 3RA2323-8XB30-1BB4 is an S0 size forward and reverse contactor combination with a coil voltage of 24V DC and a rated current of 9A. It has built-in mechanical and electrical interlocks and is suitable for forward and reverse circuits of motors in DC control systems.

Core Product Advantages and Features
24V DC coil design
The control voltage is 24V DC, which is suitable for PLC control boxes or safety circuit systems that are mainly powered by DC.
Mechanical and electrical double interlocking
The two sets of contactors, one for forward and one for reverse rotation, are interlocked and have both mechanical and electrical interlocks to prevent short circuits caused by simultaneous engagement.
Built-in 2 sets of normally open auxiliary contacts
The unit has two sets of normally open auxiliary contacts that can be directly connected to monitoring or interlocking circuits, eliminating the need for additional wiring.
The S0 has a compact and space-saving design.
It adopts the S0 standard contactor body, which is suitable for the configuration requirements of control boxes with limited space.
