Siemens 3RT2016-1AB01 Contactor

Siemens 3RT2016-1AB01 is a SIRIUS 3RT2 power contactor, size S00, with a 24 V AC coil for integration into 24 V control circuits in industrial panels. This 3-pole device is rated for AC-3e/AC-3 duty and can switch up to 9 A and handle up to 4 kW at 400 V, with a 50/60 Hz coil operating frequency. It includes one normally open auxiliary contact and uses screw terminals, offering straightforward wiring in compact enclosures. Because it belongs to the Siemens 3RT2 family, it shares standard mounting dimensions and supports compatible auxiliary blocks for expanded signaling options. Typical applications include motor control and general load switching in 400 V AC systems, where a 24 V AC coil energizes the main contacts to drive motors, conveyors, pumps, and other automation loads in machine and process control environments.
