Siemens SIRIUS 3RT2016-2BA41 Power Contactor AC-3e/AC-3, 9A, 4kW, 12V DC, 1 NO Aux, Spring-Loaded Original Brand New

Overview

The Siemens SIRIUS 3RT2016-2BA41 is a high-performance power contactor engineered for reliable switching of motors and other industrial loads. As part of the SIRIUS modular system, it offers a compact design (size S00) while delivering robust functionality. This 3-pole contactor is rated for AC-3e/AC-3 operation, handling currents up to 9A and motor power up to 4kW at 400V.

The 12V DC operating voltage makes it suitable for applications with DC control circuits, while the integrated 1 NO auxiliary contact provides additional flexibility for signaling and control functions. The innovative spring-loaded terminals ensure fast, secure, and vibration-proof wiring, significantly reducing installation time and maintenance efforts.

Benefit

• Compact and Space-Saving: The S00 size allows for high-density installation in control cabinets, maximizing available space.
• Reliable Performance: Designed for demanding industrial environments, ensuring long-term operational stability and safety.
• Reduced Installation Time: Spring-loaded terminals eliminate the need for tools, allowing for quick, easy, and secure wiring.
• Vibration-Resistant Connection: The spring-loaded technology ensures a consistently tight connection, even in applications with high vibration.
• Versatile Application: Ideal for a wide range of motor and resistive load switching applications in various industries.
• Integrated Auxiliary Contact: The built-in 1 NO auxiliary contact simplifies control circuit design and reduces the need for external components.

Function

The Siemens 3RT2016-2BA41 functions as a core component in motor control circuits. It is used to switch motor loads on and off, protecting them from overload when used in combination with an overload relay. Its primary functions include:

• Motor Switching: Safely and reliably switching 3-phase motors.
• Resistive Load Switching: Suitable for controlling other resistive loads such as heating elements.
• Control Integration: The 12V DC coil allows for seamless integration into low-voltage DC control systems.
• Signaling: The 1 NO auxiliary contact provides a signal to the control system indicating the contactor’s state (open or closed).
