Why Choose the Lovato DOLSW7.5110 Standard DOL Starter?
The Lovato DOLSW7.5110 is a standard direct-on-line (DOL) motor starter designed for three-phase motors rated up to 7.5 kW. Supplied as a complete enclosed starter with an integrated isolator, it provides a practical solution for local motor starting, stopping, isolation and overload protection in industrial and commercial applications.
This L-Starter model features a 110 V AC control voltage and overload protection suitable for motor currents up to 18 A. The direct-on-line arrangement provides straightforward contactor-controlled motor starting, while the integrated isolator allows the starter and connected motor circuit to be locally isolated for maintenance and servicing.
Housed in a durable plastic enclosure, the DOLSW7.5110 combines the principal motor-control components into a convenient pre-configured assembly. This reduces the need to source and assemble separate contactors, overload relays, operator controls, enclosures and isolating devices when installing a standard DOL motor-control solution.

Integrated DOL Motor Starting, Protection and Isolation
Direct-on-line starting is a proven method of controlling suitable three-phase induction motors by connecting the motor directly to the supply through an electromagnetic contactor. The Lovato DOLSW7.5110 packages this functionality with overload protection for motors up to 7.5 kW, providing a straightforward solution where the electrical supply and driven equipment permit full-voltage starting.
The addition of an integrated isolator distinguishes the DOLSW starter from a basic enclosed DOL starter by providing local electrical isolation at the motor-control point. This is particularly useful on pumps, fans, conveyors and machinery where operators or maintenance personnel require a convenient means of isolating the motor circuit before inspection or servicing.
Typical Applications
- Three-phase motors up to 7.5 kW.
- Industrial pumps and pumping systems.
- Fans, blowers and ventilation equipment.
- Conveyors and material-handling machinery.
- Compressors and general industrial machinery.
- OEM equipment requiring local motor starting and isolation.
