Product Positioning

The SIRIUS 3RW4436-6BC34 is a soft starter with a voltage rating of 200-460V. With a standard wiring rated current of 145A, it is suitable for medium and large motors and is ideal for factories to gradually replace traditional star-delta starter panels with production line equipment.

Core Product Advantages and Features

Replace traditional star-shaped start

Replacing mechanical star-delta switching with electronic soft start reduces current surges and contact wear during switching.

Screw terminals are easy to maintain

The main circuit uses busbar connections and the control circuit uses screw terminals, making on-site wiring and regular maintenance easier.

Adjustable current limit

The starting current can be adjusted by a limit factor according to the motor characteristics to avoid putting excessive burden on the power supply system at the moment of startup.

Inner triangle expansion elasticity

When higher power is required, an internal delta connection can be adopted, and the rated current can be increased to 251A to meet upgrade needs.
