FAQ

The primary differences are in design and efficiency. The 3RT2 series is more compact, has a wider operating temperature range, and offers better energy efficiency. However, for direct replacement in existing systems, the 3RT1016-1AP02 provides identical electrical ratings and physical mounting, ensuring a seamless fit without panel modifications.

Yes, you can. For single-phase applications, it is common practice to wire the main contacts in series to share the load, which can enhance the lifespan of the contacts. Please consult the official Siemens documentation for correct wiring diagrams for single-phase motor control.

The size designation (e.g., S00, S0, S2) in Siemens SIRIUS contactors refers to the physical dimensions and the current/power rating of the device. Size S00 is the most compact size in the series, typically used for controlling smaller motors up to approximately 4 kW (at 400V AC). This standardization helps in panel design and component selection.
