IEC Magnetic Contactor for Motor Control
The SIEMENS 3RT23171AB00 is a four-pole IEC magnetic contactor designed for switching inductive loads up to 12 A and resistive loads up to 22 A. It operates on a 24 V AC coil and provides four normally open main contacts in a non-reversing configuration. The unit belongs to the SIRIUS 3RT23 series and fits frame size S00 for standard industrial motor-starting applications.
Sustained Load Behaviour
Under continuous operation the contactor maintains its rated inductive and resistive current limits without derating. The 24 V AC coil draws steady power while held in, and the screw terminals keep contact resistance stable over long duty cycles. The auxiliary contact block supplies 2NO/2NC circuits for status feedback or interlocking during extended run periods.
Build Quality and Mounting
The compact housing measures 3.08 in high by 1.97 in wide and carries no NEMA enclosure rating, so it must be installed inside a suitable cabinet. Mounting options include DIN rail or direct surface fixing, giving flexibility for panel layouts. Screw terminals accept standard ferrules or solid wire for reliable field wiring.

Questions about this item
How much heat and power does the 24 V AC coil draw during continuous operation?
The coil is rated for 24 V AC; the contactor handles up to 12 A inductive and 22 A resistive load, and the compact S00 frame limits heat rise in the enclosure.
What auxiliary wiring or control circuit must already be in place for the 24 V AC coil to operate?
A 24 V AC control supply capable of energising the coil, plus screw-terminal wiring to the four auxiliary contacts (2 NO / 2 NC) for feedback or interlocking.
Will this IEC S00 contactor fit on the same DIN rail and work with my existing 22 A resistive motor starters?
Yes, it mounts on standard DIN rail or surface, uses screw terminals, and its 22 A resistive rating matches existing starters of the same current class.
