Siemens 3RT2016-2BF41 Power Contactor, 9A, 4kW, 110V DC, S00 Original Brand New

Overview: Siemens 3RT2016-2BF41 SIRIUS Power Contactor

The Siemens 3RT2016-2BF41 is a high-performance 3-pole power contactor from the globally recognized SIRIUS modular system, specifically the 3RT2 series. Designed for switching motors and other resistive loads in industrial control applications, this device ensures high contact reliability within a compact, space-saving design (Size S00).

It is rated for a 9 Amp operational current (AC-3e/AC-3) and a power rating of 4 kW at 400 V. A key feature is its 110 V DC operating coil, which provides reliable, low-power control. The integrated spring-loaded terminals ensure a fast, vibration-proof, and maintenance-free connection, significantly reducing wiring time compared to screw terminals.

Benefit

1. Fast, Vibration-Proof Wiring: The advanced spring-loaded terminal technology allows for quick, reliable, and maintenance-free connections, ideal for environments with high vibration or for projects requiring faster assembly.
2. Compact, Space-Saving Design: As a Size S00 contactor, the 3RT2016-2BF41 saves valuable panel space, contributing to smaller, more efficient control cabinets.
3. High Reliability: Part of the established Siemens SIRIUS modular system, this contactor offers excellent contact reliability and long mechanical service life (typically 30,000,000 switching cycles).
4. DC Coil Efficiency: The 110 V DC coil provides consistent and reliable switching performance, often preferred in specific industrial control systems.
5. Simplified Configuration: The integration of 1 Normally Open (NO) auxiliary contact reduces the need for additional add-on components in many standard applications.
6. Global Compliance: The device is climate-resistant and approved for worldwide use (IEC and UL/CSA), making it suitable for global applications and IE3/IE4 motor efficiency standards.

Function

The Siemens 3RT2016-2BF41 Power Contactor functions as an electromechanical switching device primarily used for:

• Switching 3-Phase Motors: It reliably switches the main circuit of three-phase motors up to 4 kW (at 400V).
• Switching Resistive Loads: It is also suitable for controlling other electrical loads, such as heating elements and lighting circuits.
• Control Integration: The 110V DC coil allows the device to be seamlessly integrated and controlled by Programmable Logic Controllers (PLCs) or other DC control systems.
