Reliable Motor Starting with Manual and Automatic Control

Direct-on-line starters such as the IMO DOLH10230 are used to start electric motors by applying full line voltage directly to the motor terminals. This provides a simple and reliable starting method for suitable motors where high starting torque and straightforward control are required.

The Hand-Off-Auto selector makes the DOLH10230 especially useful in systems where a motor may need to be controlled locally by an operator or automatically by an external control device. This makes it suitable for pump control, fan systems, process equipment and machine installations where flexible operating modes are required.

Typical Applications

• Pumps and water treatment equipment.
• Fans, blowers and ventilation systems.
• Compressors and small industrial machinery.
• Conveyors and material handling equipment.
• Automatic motor control circuits.
• Industrial control panels and motor control installations.
• Agricultural, commercial and light industrial motor systems.
