Siemens 3RT1317-1AK60 NEMA Contactor Four Pole

Siemens 3RT1317-1AK60 is a four-pole NEMA contactor rated for up to 690 V and 22 A, designed to interrupt high‑voltage three‑phase loads in industrial control panels. The four main contacts enable simultaneous switching of multiple conductors in typical three‑phase networks, providing clear isolation when the device is de‑energized. As a member of Siemens’ power contactor lineup, it is intended for demanding automation environments where reliable on/off control of substantial loads is required. The 3RT1317-1AK60 designation identifies this exact four‑pole variant within the family, aligning with standard mounting and wiring conventions used for Siemens NEMA contactors. This model supports integration in control cabinets and machine circuits that demand durable operation and consistent performance under load, making it suitable for applications such as motor control and heavy equipment switching in industrial settings.
