Industrial Motor Starter
The SIEMENS 3RA23288XB301AK6 is an IEC magnetic contactor built for three-phase motor control in industrial machinery. It carries a 38 A inductive and 50 A resistive full-load rating on a 110/120V AC coil, making it suitable for automation panels that demand reliable switching. The unit mounts on DIN rail or surface and uses screw terminals for secure wiring.
Sustained Load Operation
Under continuous duty the contactor maintains its rated 38 A inductive and 50 A resistive currents without derating, thanks to the SIRIUS 3RA23 frame S0 design. The 3-pole main circuit and 2NO/2NC auxiliary contacts (three auxiliary contacts total) provide consistent signalling for interlocks and status feedback during extended run cycles. Reversing capability is integrated, allowing forward and reverse motor operation from a single compact device.
Pre-Installation Checks
Verify that your control circuit supplies 110/120V AC to match the coil voltage before ordering. Confirm the panel has DIN rail or flat surface space measuring at least 4.41 in height by 3.82 in width for the unit footprint. Ensure the screw terminal wire gauge suits your feeder conductors and that the 3-pole configuration matches the motor winding connections required.

Questions about this item
How much heat does the 38 A inductive load generate during continuous operation?
The contactor is rated for 38 A inductive and 50 A resistive full-load current; heat rise depends on the enclosure ventilation and duty cycle in your installation.
What control voltage must my panel supply to energise the 110/120V AC coil?
The coil operates on 110 V to 120 V AC; ensure your control transformer or supply matches this range before wiring.
Will the screw terminals accept the same wire gauge as my existing S0 frame starters?
Yes, the unit uses screw terminals on an S0 frame, so wire preparation matches other SIRIUS 3RA23 S0 devices you may already have.
