3RW4444-6BC34
The Siemens SIRIUS 3RW4444-6BC34 is the 115V control voltage version of the 3RW4444, with a rated current of 215A, 75hp at 230V and 150hp at 460V, and an operating voltage of 200-460V AC. It features screw terminal wiring and a built-in bypass contact.
Product Positioning
The 3RW4444-6BC34 and 3RW4444-6BC44 are models with the same current rating. The difference is that the control voltage is changed to 115V AC, which is convenient for connecting to production lines with low-voltage control systems.
Core Product Advantages and Features
115V control power supply
The control circuit adopts a 115V AC design, which is suitable for automated factories that are accustomed to low-voltage control.
215A rated current
It can meet the motor power requirements of 75hp at 230V and 150hp at 460V.
Bypass connection design
