About the DOL Motor Starter

The Direct-On-Line (DOL) starter is a widely used, simple and effective method to start three-phase motors. When energized, it connects the motor directly to the supply, providing full line voltage at startup. This starter is ideal where the supply network can handle the inrush current — common for pumps and many industrial motors.

Our DOL starter features a heavy duty 4-pole contactor for dependable switching, a reliable thermal overload relay for motor protection, and silver cadmium oxide contacts that resist arcing under demanding conditions. Encased in a deep-drawn CR sheet steel housing, this starter is built for extended service in commercial and agricultural settings.

Applications: Submersible pump motor control, irrigation pumps, small compressors, conveyor motors, and light manufacturing equipment.

Frequently Asked Questions

Q: What motor HP does this starter support?

A: Designed for motors up to 15 HP on a 3-phase 415V supply. For larger motors or special starting requirements (soft start, star-delta), consider the appropriate starter panel.

Q: Does it provide overload protection?

A: Yes — it includes a thermal bi-metallic overload relay to protect the motor from sustained overload conditions.

Q: Can it be mounted outdoors?

A: The CR sheet enclosure is sturdy, but for direct outdoor exposure we recommend mounting inside a protective cabinet or under a canopy and following local IP rating requirements.
