IEC Magnetic Contactor, 2NC-2NO, 110V-120V AC, 3 P, Non-Reversing, Screw 3RT20161AK643MA0

The Siemens IEC Magnetic Contactor is a 3-pole, non-reversing, electrically operated switching device rated for operation within IEC-standard applications. It uses a 110–120 V AC coil to operate the main contacts and includes auxiliary contacts configured as 2 NO/2 NC (4 total). The unit is part of the SIRIUS 3RT Safety Contactors series with frame size S00, uses screw terminals, and is supplied with a permanent mounted auxiliary contact. It has no enclosure (IP20) and a maximum voltage rating of 690 V AC, supporting 50/60 Hz operation. The contactor supports 9 A inductive and 22 A resistive full-load currents and offers a long mechanical life, with 30,000,000 cycles.
