Product Positioning

The SIRIUS 3RW4435-6BC35 is suitable for voltage ranges of 400-600V and is a model with a smaller current rating in the 3RW44 series. It is suitable for soft-start requirements of small and medium-sized three-phase motors such as conveyors and mixers.

Core Product Advantages and Features

Covering higher voltage levels

With an operating voltage of up to 600V, it is suitable for some industrial or export equipment that requires higher voltage power supply.

115V control circuit

The control power supply is 115V AC, which is compatible with the voltage of some existing distribution panel control circuits, making modification and replacement relatively convenient.

Three temperature rating references

It offers rated currents at three ambient temperatures: 40°C, 50°C, and 60°C, facilitating precise selection based on on-site heat dissipation conditions.

Internal delta wiring upgrade

If a larger motor is required, the current can reach 203A after switching to the internal delta wiring, eliminating the cost of changing the model.
