Siemens 3RT1065-6AF36 Power Contactor, 265A, 132kW, 110-127V AC/DC, 3-Pole Original Brand New

Overview 

The Siemens 3RT1065-6AF36 is a robust 3-pole power contactor engineered for switching and controlling electric motors and other loads up to 132 kW at 400 V. It’s designed for AC-3e/AC-3 applications, handling a substantial current of 265 A. This model features a conventional drive and a versatile control voltage of 110-127 V AC/DC.

Its main circuit connects via a busbar, while the control and auxiliary circuits use screw terminals, offering flexible installation options. The contactor includes 2 normally open (NO) and 2 normally closed (NC) auxiliary contacts, providing additional functionality for control and signaling purposes.

Features & Benefit

• High Performance: Capable of handling significant loads up to 265 A and 132 kW, making it suitable for demanding industrial applications.
• Versatile Control: Operates on a wide control voltage range of 110-127 V AC/DC, simplifying integration into various control systems.
• Safety & Reliability: AC-3e/AC-3 rating ensures reliable switching of motor loads, minimizing wear and tear.
• Flexible Connectivity: The combination of a busbar for the main circuit and screw terminals for the control and auxiliary circuits provides easy and secure connections.
• Integrated Auxiliary Contacts: The built-in 2 NO + 2 NC auxiliary contacts offer enhanced control and feedback capabilities without the need for additional modules.

Function

The Siemens 3RT1065-6AF36 power contactor functions as a remotely controlled switch. When the coil is energized by the 110-127 V AC/DC control voltage, the main contacts close, allowing power to flow to the connected motor or load. When the coil is de-energized, the main contacts open, interrupting the power supply. The integrated auxiliary contacts change state in tandem with the main contacts, enabling them to be used for control logic, interlocking, or signaling the status of the contactor to a PLC or other control system.
