FAQ

The 3RT2 series is the successor to the 3RT1. It offers a more compact design, higher power density, lower power consumption of the coil, and is part of the newer SIRIUS modular system, allowing for easier integration with modern overload relays and accessories.

Yes, while designed for 3-phase applications, it can be used for single-phase motors. To do so, you would typically wire the phases in series through the three main contacts to balance the load and ensure proper operation.

The size designation (e.g., S00, S0, S2) in Siemens SIRIUS contactors refers to the physical dimensions and power rating of the device. Size S0 is a common frame size that covers motor ratings up to approximately 15 kW, making it suitable for a wide range of standard industrial applications.
