Product Positioning
The 3RA1317-8XB30-1BB4 is a Siemens SIRIUS 3RA13 series S00 size forward and reverse combination starter. It adopts 24VDC coil drive and is suitable for three-phase motor forward and reverse automatic control. The current main original equipment manufacturer has been replaced by the 3RA23 series.
Core Product Advantages and Features
S00 standard size
It shares the same S00 form factor as the 3RA1315 and 3RA1316 in the same series, which facilitates standardized spare parts specification management.
24VDC coil drive
Equipped with a DC coil, it is suitable for direct drive and control by PLC output modules or DC power supplies.
Mechanical and electrical double interlock
The two sets of contactors, one for forward and one for reverse rotation, are interlocked to avoid the risk of phase-to-phase short circuits in the main circuit.
Screw terminal wiring
Both the main circuit and the control coil use screw terminals, which facilitates on-site wiring and future maintenance.
