Product Positioning

The 3RW4037-1BB15 is a SIRIUS 3RW40 series S2 frame soft starter with a rated current of 63A and a rated operating voltage of 400...600V AC, suitable for the installation needs of three-phase motors in areas with higher power supply voltage.

Core Product Advantages and Features

Wide voltage level design

Rated operating voltage ranges from 400 to 600V AC, which can meet the specifications of medium and high voltage power grids in many countries.

110-230V control power supply

The control circuit voltage is compatible with the existing 110V or 230V control box on site, eliminating the need for an additional transformer.

Screw terminal wiring

Continuing with traditional wiring methods, on-site personnel can work seamlessly together.

Standard overload protection

It has a built-in electronic overload protection function and can operate without the need for an additional thermal resistor.
