Originally discontinued by the manufacturer, it is now supplied by the 3RA2315 series.
Product Positioning
The 3RA1315-8XB30-1BB4 is a Siemens SIRIUS 3RA13 series forward and reverse contactor combination. It comes pre-assembled with dual contactor wiring and interlocking, rated for AC-3 load of 3kW/400V, and equipped with a 24V DC operating coil. It is suitable for S00 size screw terminal installation applications.
Core Product Advantages and Features
DC coil design
It uses a 24V DC operating coil, making it suitable for integration into automation systems controlled by DC power supplies.
Electrical and mechanical double interlock
By combining mechanical interlocking devices with auxiliary contact electrical interlocking, simultaneous operation of forward and reverse circuits is prevented.
Pre-assembled at the factory
The two contactors and interlocking mechanisms are assembled before leaving the factory, shortening on-site installation time.
S00 compact design
Continuing the S00 size specification, it is suitable for control boxes and distribution panels with limited installation space.
