Siemens SIRIUS 3RT2016-2AK61 Power Contactor, 9A, 4kW, 3-Pole, 110/120V AC Coil, Spring Terminal, Size S00 Original Brand New

Overview

The Siemens 3RT2016-2AK61 SIRIUS Power Contactor is a high-performance 3-pole switching device engineered for reliable motor control applications. Part of the compact and modular SIRIUS 3RT2 series, this unit is rated for an operational current of 9 A (AC-3e/AC-3) and a power rating of 4 kW at 400 V.

It features a dual-frequency control coil operating at 110 V AC (50 Hz) / 120 V AC (60 Hz) and includes one integrated normally open (1 NO) auxiliary contact. The contactor utilizes time-saving, vibration-proof spring-loaded terminals for quick and secure wiring of both main and auxiliary circuits, and its small Size S00 design ensures maximum space efficiency in control panels.
