The Siemens 3RT1065-6AF368K is a heavy-duty SIRIUS 3RT1 power contactor supplied without an operating coil, allowing users to select and order the appropriate AC or DC coil separately according to the application requirements. Designed for switching high-power motors and industrial loads, this contactor delivers outstanding reliability and long service life in demanding industrial environments.
The contactor features 3 main power poles along with 2 Normally Open (2NO) and 2 Normally Closed (2NC) auxiliary contacts, making it suitable for motor control, signaling, interlocking, and automation applications. It is rated for 265 A (AC-3) and can control motors up to 132 kW at 400 V AC. The busbar main terminals and screw terminals for the control and auxiliary circuits ensure secure electrical connections and simplified installation.
Manufactured to Siemens' SIRIUS quality standards, the 3RT1065-6AF368K is ideal for use in motor control centers (MCCs), power distribution systems, industrial automation, HVAC equipment, pumps, compressors, conveyors, and OEM machinery where reliable switching performance is essential.
