SIEMENS 3RA23158XB301BB4 Reversing Contactor
This SIEMENS IEC magnetic contactor is a 3-pole reversing starter with a 24V DC coil. It is built for DIN rail or surface mounting in a frame size S00 and carries the SIRIUS 3RA23 series designation. The unit includes two normally closed auxiliary contacts and uses screw terminals for wiring connections.
Suits 24V DC control panels needing motor reversal
This contactor fits panels that switch three-phase loads up to 7 A inductive or 18 A resistive and require a reversing function. It is not for applications needing normally open auxiliary contacts, a different coil voltage, or a non-reversing starter. Builders without DIN rail or surface mounting provisions should look elsewhere.
Coil voltage fixes compatibility
The 24V DC coil voltage is the single specification that determines whether this contactor matches the control circuit. Verify that the panel supplies exactly 24V DC before purchasing.

Questions about this item
Should I choose the 24V DC coil version or another coil voltage for my control circuit?
This contactor uses a 24V DC coil, so select it when your control circuit supplies 24V DC; other coil voltages would require a different part number.
What does the 7 A inductive full load current mean for my motor application?
The 7 A inductive rating is the maximum current the main contacts can switch for inductive loads such as motors under IEC utilization categories.
How does the screw terminal connection affect installation on a DIN rail?
Screw terminals accept stripped wire directly, and the unit mounts on standard DIN rail or via surface mounting using the integrated feet.
