Siemens 3RT2016-1AK62 Three-Phase Contactor

Siemens 3RT2016-1AK62 is a compact SIRIUS power contactor, a three-pole device designed for AC-3e/AC-3 motor control, rated to switch up to 9 A and handle up to 4 kW at 400 V. The coil operates at 110 V AC for 50 Hz systems and 120 V AC for 60 Hz systems, enabling reliable operation across common European and North American supplies; a single normally closed auxiliary contact provides a simple signaling or interlocking function. The unit uses screw-terminal connections and is classified as size S00, which suits compact control panels and enclosures. With a net weight of about 0.231 kg, the 3RT2016-1AK62 provides a lightweight yet robust option within the SIRIUS 3RT lineup for demanding industrial environments. Typical uses include initiating and stopping 3-phase motors in conveyors, pumps, fans, machine tools, and automation equipment, where reliable AC-3 switching of motor loads is required and the compact S00 form factor is preferred.
