Siemens SIRIUS 3RT1065-6AD36 Power Contactor AC-3e/AC-3 265A, 132kW, 42-48V UC Coil, 3-Pole, Busbar Main Connection Original Brand New

Overview: Siemens 3RT1065-6AD36 High-Performance Contactor

The Siemens SIRIUS 3RT1065-6AD36 is a robust, high-performance 3-pole power contactor from the globally recognized SIRIUS modular system. Designed for switching electric motors and high-current loads up to 265 Amps (AC-3e/AC-3), this device ensures exceptional reliability for demanding industrial applications.

It is rated for a powerful output of 132 kW at 400 V AC, making it ideal for heavy-duty motor control. The unit features a versatile AC (50-60 Hz) / DC conventional drive with a wide control supply voltage range of 42-48 V UC (Universal Current). Its size S10 form factor, combined with busbar connections for the main circuit and screw terminals for the control and auxiliary circuits, ensures secure and efficient installation into modern electrical panels.

Benefit

• Exceptional Motor Control: High current rating (265 A) and power (132 kW) are perfect for reliable switching of large industrial motors.
• Flexible Control: The 42-48 V UC coil is suitable for both AC and DC control voltages, simplifying inventory and system design.
• High Reliability: Part of the proven Siemens SIRIUS system, known for long mechanical and electrical service life and operation under extreme conditions.
• Efficient Installation: Busbar connections on the main circuit simplify high-power wiring, while screw terminals for the control circuit ensure secure connections.
• Ready for IE3/IE4 Motors: Fully compatible with the latest high-efficiency motor standards.

Function

The 3RT1065-6AD36 power contactor functions as an electrically operated switch for a power circuit. Its primary role is to establish or interrupt the flow of power to a load, typically a 3-phase electric motor. The 42-48V UC control coil is energized (via the screw terminals) to close the main power contacts (connected via the busbar), starting the motor. The integrated 2 NO + 2 NC auxiliary contacts provide status feedback and interlocks for complex control systems and machinery.
