3RW4434-6BC35
The SIRIUS 3RW44 high-voltage motor has a standard rated capacity of 100 amps and 75 horsepower at 575 volts, and up to 173 amps and 150 horsepower with an internal delta connection. The main circuit covers 400 to 600 volts, and the control voltage is 115 volts, making it suitable for starting motors in North American high-voltage power grids.
Product Positioning
The 3RW4434-6BC35 is a soft starter from the Siemens SIRIUS 3RW44 series designed for 400 to 600 volt high-voltage power grids. It controls the motor starting voltage slope through thyristors, reducing the impact on the power grid when high-voltage, high-horsepower equipment is started directly.
Core Product Advantages and Features
Covering high-voltage power grid specifications
The main circuit voltage range is 400 to 600 volts, suitable for high-horsepower motors in North America and some high-voltage power distribution systems.
Double-connection power elasticity
The standard connection method provides 75 horsepower, while the internal delta connection method provides 150 horsepower, allowing one machine to meet the wiring needs of various motors.
115-volt control voltage
The control circuit uses 115-volt AC, which is convenient for integration with the existing low-voltage control panel power supply.
Screw terminals are stable for a long time
Both the main and auxiliary circuits use screw terminals, making them suitable for reliable wiring in environments with long operating times.
