IEC Magnetic Contactor for Motor Reversing
The SIEMENS 3RA23248XB301AK6 is a three-pole IEC magnetic contactor designed to reverse motor direction in industrial control circuits. It operates on a 110/120V AC coil and fits DIN rail or surface mounting within the SIRIUS 3RA23 series. The unit includes three auxiliary contacts in a 2NO/2NC configuration for status feedback and interlocking logic.
Switching limits defined by inductive
The contactor carries a full-load inductive rating of 12 A and a resistive rating of 40 A at the rated coil voltage. These figures set the practical ceiling for motor loads and heater circuits respectively. Exceeding the inductive rating risks contact welding or premature wear under motor inrush conditions.
Verify coil voltage, mounting space
Confirm the control circuit supplies 110/120V AC before ordering. The enclosure measures 4.41 in height by 3.82 in width, so check available panel depth and DIN rail spacing. Ensure the screw terminals accept your wire gauge and that the three auxiliary contacts match your control scheme.

Questions about this item
What does the 12 A inductive rating mean for motor loads?
It is the maximum current the contactor can switch for inductive loads such as motors at the rated voltage.
What does the 40 A resistive rating indicate in practice?
That figure applies to non-inductive loads such as heating elements at the rated voltage.
How does the IEC frame size S0 affect installation on DIN rail?
The S0 frame determines the physical footprint and mounting pitch for standard DIN rail or surface mounting.
