Siemens AG 3RT1016-1AK61 Electrical Contactor

Siemens 3RT1016-1AK61 is a 3-pole Sirius power contactor designed for AC-3 motor loads, featuring a 110/120 VAC coil (50 Hz / 60 Hz) and a 3 NO main contact configuration with 1 NO auxiliary contact. In AC-3 service at 400 VAC it carries 9 A (approximately 4 kW rated load), while AC-1 ratings extend to 22 A at 400 VAC, offering versatile control for different motor-start scenarios. The unit uses size S00 with screw terminals and is compatible with DIN rail mounting, delivering robust, long-life performance with a mechanical life rated around 30,000,000 switching cycles. Typical applications include starting and stopping three-phase motors in industrial controls, pumps, fans, and conveyors, where a compact, reliable 110/120 VAC coil and three-pole switching answer demanding panel‑mounted control needs. As part of Siemens’ Sirius line, the 3RT1016-1AK61 provides a proven, space-efficient solution for panel builders and integrators seeking a durable, easy‑wire control device with clearly defined AC-3/AC-1 ratings and a single NO auxiliary contact to support signaling or interlock functions.
