Why Choose the Lovato DOLSW11024 11 kW Direct-On-Line Starter with Isolator?
The Lovato DOLSW11024 is a standard enclosed direct-on-line (DOL) motor starter with built-in isolator, designed for straightforward control and isolation of three-phase motors. Part of the UK-manufactured Lovato L-Starter range, it is rated for 11 kW motors at 400 V with a maximum AC-3 motor current of 25 A.
This starter combines direct-on-line motor switching with an integral isolator in a plastic enclosure, providing a convenient motor-control solution for machinery, pumps, fans and other fixed-speed industrial equipment. The integrated isolator provides a local means of electrically isolating the motor starter for maintenance and servicing procedures.
The DOLSW11024 requires a compatible Lovato RF38 thermal overload relay, selected separately according to the motor full-load current. This allows the overload setting to be matched to the connected motor while retaining the convenience of a pre-assembled enclosed starter with local control and isolation.
Key Advantages
- 11 kW DOL motor starter for three-phase motor applications.
- Maximum 25 A AC-3 motor current.
- Built-in isolator provides convenient local electrical isolation.
- Durable plastic enclosure for standalone installation.
- Standard direct-on-line starting provides simple and dependable motor control.
- Designed for a separately selected Lovato RF38 thermal overload relay.
- Overload relay can be selected specifically to suit the motor full-load current.
- Part of the UK-manufactured Lovato L-Starter range.
Key Features
- Lovato Electric L-Starter motor starter.
- Direct-on-line (DOL) starting method.
- Integral isolator.
- 11 kW motor power at 400 V.
- 15 HP motor rating.
- 25 A maximum AC-3 motor current.
- Three-phase motor-control application.
- Plastic enclosed construction.
- Designed for RF38 series thermal overload relays.
- Overload relay is selected according to motor full-load current.
- Suitable for industrial machinery and plant motor-control applications.
Direct-On-Line Motor Control with Integrated Isolation
A direct-on-line starter applies the full supply voltage to the motor through a contactor, providing a simple and widely used starting method for fixed-speed three-phase induction motors. The DOLSW11024 adds an integral isolator to the standard starter arrangement, combining motor control and local electrical isolation in one enclosed assembly.
Motor overload protection is provided by installing the appropriate RF38 thermal overload relay. Lovato specifies that the overload relay for DOL starters should be selected and adjusted according to the motor's actual full-load current. For a typical 11 kW application, the RF38 range includes the RF38 2300 with a 17–23 A adjustment range, but final selection must be based on the motor nameplate current.
Typical Applications
- Industrial pumps and pumping systems.
- Fans and ventilation equipment.
- Conveyors and materials-handling machinery.
- Compressors and fixed-speed motor loads.
- Workshop and manufacturing machinery.
- Process equipment requiring local motor isolation.
- Industrial motor-control installations.
- Standalone machinery requiring enclosed DOL starting.
