Siemens SIRIUS 3RT2016-2XB41-0LA2 Traction Contactor 9A, 4kW, 24-34V DC, Spring Terminal, Size S00 Original Brand New

Overview

The Siemens 3RT2016-2XB41-0LA2 is a high-performance SIRIUS traction contactor designed for demanding switching applications, particularly suitable for railway technology and extended operating ranges. As part of the SIRIUS 3RT2 series, this robust 3-pole power contactor is rated for switching alternating current loads up to 9 A (AC-3e/AC-3) / 4 kW at 400 V.

It features a cutting-edge solid-state operating mechanism that guarantees reliable switching across an extended control supply voltage range of 24-34 V DC (0.7 to 1.25* Uc). The compact Frame Size S00 ensures space-saving installation in control cabinets.

Benefit

1. High Reliability in Critical Applications: Specifically designed as a traction contactor for environments requiring an extended operating voltage range (0.7-1.25* Uc), making it perfect for unstable power supplies like those found in railway applications.
2. Extended DC Control Range: The solid-state operating mechanism allows for reliable switching with a wide 24-34 V DC control voltage, offering greater flexibility and stability than standard contactors.
3. Space-Saving Design: The compact Size S00 minimizes the footprint in your electrical panel, maximizing panel space.
4. Integrated Surge Protection: The built-in varistor protects the coil and surrounding circuitry from voltage peaks, increasing the contactor’s lifespan and system reliability.
5. Fast & Secure Wiring: Spring-loaded terminals provide vibration-proof, maintenance-free, and rapid wiring, significantly reducing installation time compared to screw terminals.

Function

The 3RT2016-2XB41-0LA2 functions as a primary switching device for connecting and disconnecting three-phase AC loads, typically electric motors. The core functionality is as follows:

1. Switching: Upon receiving a control signal (24-34 V DC), the solid-state operating mechanism energizes the coil, closing the 3 main contacts to supply power to the motor or load.
2. Protection: The integrated varistor suppresses inductive voltage spikes generated when the coil is de-energized, protecting the control system components (e.g., PLC outputs).
3. Signaling/Interlocking: The integrated 1 NO auxiliary contact can be used for feedback signals to the control system or for interlocking other components, indicating the main contactor’s status.
