Siemens 3RT2016-1AF02 Three-Phase AC Contactor

Siemens 3RT2016-1AF02 is a compact, 3-pole power contactor designed for AC-3e/AC-3 duty. It provides three normally open main contacts and one normally closed auxiliary contact for signaling or interlocking, all in a small S00-size frame with screw-terminal connections. The coil operates at 110 V AC with a 50/60 Hz supply, allowing direct interfacing with standard control circuits. On the high-voltage side, the device is rated for motor loads up to 9 A and up to 4 kW at 400 V, making it suitable for starting and stopping three-phase motors and other AC-3 loads. This Siemens part is built for dependable operation in industrial control panels where space is tight but reliable switching is required.
