Siemens 3RT2016-2AN21 SIRIUS Power Contactor, 9A, 4kW, 220V AC, Size S00 Original Brand New

Overview

The Siemens 3RT2016-2AN21 is a high-performance SIRIUS 3-pole power contactor designed for reliable switching of motors and other electrical loads. As part of the Siemens SIRIUS modular system, this contactor offers a compact design (Size S00) and is engineered for easy and secure installation. It is rated for AC-3e/AC-3 applications, handling a current of 9 A and power up to 4 kW at 400 V. The 220 V AC control voltage ensures compatibility with standard industrial power systems.

Key Features & Benefit

• Compact & Space-Saving Design: The small S00 size allows for high-density installation in control panels, optimizing cabinet space.
• High Performance: Rated for 9 A (AC-3e/AC-3) and capable of switching motors up to 4 kW at 400 V, making it suitable for a wide range of industrial applications.
• Secure & Fast Wiring: Features spring-loaded terminals, which provide a vibration-proof connection and significantly reduce wiring time compared to screw terminals. This ensures a reliable electrical connection without the need for constant retightening.
• Integrated Auxiliary Contact: Comes with a pre-installed 1 NO (Normally Open) auxiliary contact, providing a signaling or interlocking function, which is essential for complex control circuits.
• Efficient and Reliable Operation: Designed for long-term use with a robust build quality and a low-power 220 V AC coil, minimizing energy consumption and heat generation.
• Easy Integration: Compatible with the extensive Siemens SIRIUS modular system, allowing for seamless expansion with overload relays, auxiliary switches, and other accessories.

Function

The Siemens 3RT2016-2AN21 power contactor acts as an electrically operated switch. When the 220 V AC control voltage is applied to its coil, it generates a magnetic field that pulls the main contacts together, allowing power to flow to the connected load (e.g., an electric motor). When the voltage is removed, the contacts open, interrupting the circuit. The integrated 1 NO auxiliary contact closes simultaneously with the main contacts, providing a status signal to a PLC or another control device.
