The Siemens SIRIUS 3RA6250-1EE33 is a compact reversible starter with built-in dual contactor interlocking, enabling forward and reverse switching of motors. It has a 690V withstand voltage, an adjustable overload capacity of 8 to 32A, and supports motor power up to 15kW at 400V. It features screw-on terminals, IP20 protection, and is suitable for bidirectional operation of high-power motors.
Product Positioning
The 3RA6250-1EE33 is a compact reversible starter from the Siemens SIRIUS 3RA6 series. It offers a high current overload setting range and features a built-in dual contactor interlock, making it suitable for high-power three-phase motors that require forward and reverse operation.
Core Product Advantages and Features
Dual contactor interlock design
It contains dual contactors with mechanical and electrical interlocks, and a single module can complete the forward and reverse switching of the motor without the need for additional interlock components.
High current overload setting
With an adjustable overload current range of 8 to 32A, it is suitable for high-power three-phase motors up to 15kW at 400V.
Screw-mounted terminals
The main circuit adopts a screw-type terminal design, which has excellent load-bearing capacity and is suitable for wiring requirements with large current.
Simplified integrated architecture
A single module integrates start-up protection, contactor switching, and overload protection, replacing the traditional multi-component assembly configuration.
