abb acs310 inverter variable speed drive three phase 11kw 50.82a ip20

Why Choose the ABB ACS310-03E-50A8-2 General Purpose Drive?

The ABB ACS310-03E-50A8-2, ABB product ID 3AUA0000039624, is a compact and dependable AC variable frequency drive (VFD) developed for variable-torque applications such as pumps and fans. As part of the ABB ACS310 general purpose drive series, it combines dedicated pump and fan functionality with straightforward commissioning and integrated communication capabilities for building services and industrial automation.

The ACS310 series includes application-oriented functions such as built-in PID control, energy-efficiency counters and embedded Modbus communication. These capabilities make the drive particularly suitable for applications where motor speed needs to follow changing process demand, helping improve system control while reducing unnecessary motor energy consumption.

With a rated output power of 11 kW, a nominal output current of 50.8 A and a three-phase 200–240 V AC supply, the ACS310-03E-50A8-2 is designed for substantial low-voltage pump, fan and general variable-torque motor applications. The drive uses an R4 frame and provides IP20 protection for cabinet installation.

Efficient Control for Pumps and Fans

Variable frequency drives such as the ABB ACS310 regulate motor speed by varying the frequency and voltage supplied to the motor. In pump and fan systems, this enables output to follow actual process demand rather than relying on continuous full-speed motor operation combined with mechanical throttling, helping improve process control and reduce energy consumption.

The ACS310 series is particularly suited to variable-torque applications. Built-in PID control enables the drive to respond automatically to process variables such as pressure, flow or temperature, while embedded Modbus connectivity facilitates integration with building management, PLC and industrial automation systems.

Typical Applications

• Centrifugal pumps and pumping systems.
• Supply and extract fans.
• HVAC and building-services equipment.
• Booster pump systems.
• Cooling and ventilation equipment.
• Water and wastewater applications.
• Industrial process pumps and fans.
• General variable-torque motor applications.
