Product Positioning

The 3RW4036-1BB15 is a standard soft starter with a lower current rating in the SIRIUS 3RW40 series S2 frame, with a rated operating voltage extending to 400...600V AC, suitable for small and medium power motors in higher voltage power grids.

Core Product Advantages and Features

Wide voltage level

The rated operating voltage covers up to 600V AC, which meets the field requirements of higher voltage power supply systems.

110-230V control power supply

No 24V transformer is required; the voltage of the existing control box on site can be used directly for power supply.

Standard overload protection

Built-in electronic overload protection allows it to operate without the need for an external thermal resistor.

Screw terminal wiring

Continuing with traditional wiring methods, on-site construction personnel do not require additional training.
