Why Choose the Lovato M3P03270400 Star-Delta Starter?
The Lovato M3P03270400 is an enclosed star-delta motor starter designed for controlled starting of compatible three-phase motors. By starting the motor in star before switching to delta for normal operation, the starter helps reduce starting current compared with direct-on-line starting.
The M3P03270400 has a maximum IEC operating current of 50 A at voltages up to 440 V and an IEC motor power rating of 25 kW at 400 V. It incorporates START and STOP/RESET pushbuttons and uses 400 V AC 50/60 Hz contactor coils for the control circuit.
Designed for starting times of up to 12 seconds and a maximum operating frequency of 30 operations per hour, the M3P03270400 provides an integrated solution for industrial star-delta motor starting. Its enclosure provides IP65 frontal protection, while the required RF38 series thermal overload relay is selected separately to suit the connected motor.

Controlled Star-Delta Motor Starting
Star-delta starting is used with compatible three-phase motors to reduce the current drawn during acceleration. The motor is initially connected in star and is subsequently switched to delta for normal running, providing a well-established starting method for industrial motor applications.
The Lovato M3P03270400 integrates the contactors, auxiliary contacts and operator controls required for star-delta starting within an enclosed assembly. Its starting sequence supports a starting time of up to 12 seconds and a maximum of 30 operations per hour, while an 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.
