Why Choose the Lovato M3P03870230 Star-Delta Starter?
The Lovato M3P03870230 is an enclosed star-delta motor starter designed for controlled starting of compatible three-phase motors. By initially connecting the motor windings in star before changing to delta for normal running, it provides a proven method of reducing starting current compared with direct-on-line starting.
The M3P03870230 has a maximum IEC operating current of 60 A at voltages up to 440 V and an IEC motor power rating of 30 kW at 400–440 V. The starter uses 230 V AC 50/60 Hz contactor coils and incorporates START and STOP/RESET pushbuttons for convenient local motor control.
Designed for starting times of up to 12 seconds and a maximum operating frequency of 30 operations per hour, the M3P03870230 combines the required contactors and auxiliary contacts in an M3PA70 enclosure with IP65 frontal protection. The thermal overload relay is selected separately from the compatible Lovato RF38 series to suit the connected motor.

Controlled Star-Delta Motor Starting
Star-delta starting reduces the current drawn during acceleration by initially connecting a compatible three-phase motor in star and subsequently switching it to delta for normal operation. This established starting method is suitable for applications where reduced starting current is required and the motor is designed for star-delta operation.
The Lovato M3P03870230 integrates the required contactors, auxiliary contacts and operator controls within an enclosed assembly. It supports starting times of up to 12 seconds and a maximum of 30 operations per hour, while a compatible RF38 series thermal overload relay can be selected separately according to the motor protection requirements.
Typical Applications
- Industrial pumps and pumping systems.
- Fans and ventilation equipment.
- Compressors and process machinery.
- Conveyors and material handling systems.
- Production and manufacturing machinery.
- Three-phase motors designed for star-delta starting.
