Product Positioning

The SIRIUS 3RW4436-6BC44 is a compact model in the Siemens 3RW44 series with a smaller current rating. Its compact design provides flexibility for standard or internal delta wiring, making it suitable for the reduced-voltage starting needs of medium-sized three-phase asynchronous motors.

Core Product Advantages and Features

Compact design

The 170x200x270mm body maintains a compact size for medium current ratings, facilitating space planning in distribution boxes.

Dual voltage power correspondence

It can be powered by 230V or 400V respectively to correspond to different motor power, flexibly adapting to the on-site power grid conditions.

Bypass contact power consumption reduction

After startup, the bypass contact is switched on to reduce the continuous heating of the thyristor and extend the service life of the components.

Internal delta wiring capacity upgrade

After switching to internal delta wiring, the current can be increased to 281A, which is suitable for motor applications with higher power ratings.
