Product Positioning

The SIRIUS 3RW4436-6BC35 is suitable for three-phase motors with higher voltage levels of 400-600V. It can flexibly meet different power requirements through standard or internal delta wiring methods and has a complete bypass and protection mechanism.

Core Product Advantages and Features

High voltage level corresponding

The operating voltage ranges from 400 to 600V, making it suitable for mechanical equipment that uses higher voltage power supplies both domestically and internationally.

Dual-wire mode switching

Choose either standard or internal delta wiring according to the motor wiring requirements; the same model can be used for different power ranges.

Multi-segment stopping curve

In addition to normal free stop, it also provides ramp deceleration and torque control stop to reduce mechanical impacts such as water hammer.

Bypass energy-saving operation

After startup, mechanical bypass contacts replace thyristor conduction to reduce energy loss during steady-state operation.
