Why Choose the Lovato BFA03270024 Star-Delta Starter?
The Lovato BFA03270024 is a complete open-frame star-delta motor starter designed to reduce starting current when controlling three-phase induction motors. Part of the Lovato Electric BF range, it provides an assembled solution for industrial motor-starting applications requiring dependable electromechanical control.
The starter has a maximum IEC operational current of 50 A and supports three-phase motor ratings up to 25 kW at 400 V AC. Its contactors use a 24 V AC, 50/60 Hz control coil, making the assembly suitable for control circuits operating at this voltage.
Designed for starting periods of up to 12 seconds and a maximum of 30 operations per hour, the BFA03270024 is suitable for controlled-duty industrial machinery. It is supplied without a thermal overload relay, allowing the correct overload device to be selected separately for the motor.

Controlled Starting for Three-Phase Motors
A star-delta starter initially connects a compatible motor’s windings in star configuration to reduce the current drawn during acceleration. After the timed starting period, the circuit changes to delta configuration so the motor can operate at its normal running voltage and power.
This starting method is commonly used where reduced inrush current is required and the driven machine can accelerate with reduced starting torque. The BFA03270024 must be installed with suitable upstream short-circuit protection and a correctly selected thermal overload relay.
Typical Applications
- Industrial pumps and pumping systems.
- Fans and ventilation equipment.
- Compressors with suitable starting characteristics.
- Conveyors and material-handling systems.
- Processing and production machinery.
- Industrial motor-control panels.
