Why Choose the Lovato BFA08070024 Star-Delta Starter?
The Lovato BFA08070024 is a complete open-frame star-delta motor starter designed for controlled starting of three-phase induction motors in industrial machinery and automation systems. Part of the Lovato BFA electromechanical starter series, it provides a maximum IEC operating current of 140 A and is suitable for motors rated up to 75 kW at 400 V.
Star-delta starting reduces the current drawn during motor acceleration compared with direct-on-line starting by initially connecting the motor windings in star before changing to delta for normal operation. The BFA08070024 provides a factory-coordinated contactor assembly for this starting method, helping simplify the construction of high-power industrial motor control panels.
The BFA08070024 uses 24 V AC, 50/60 Hz contactor coils and is designed for starting times up to 12 seconds with a maximum of 30 operations per hour. The open-frame format is intended for installation inside a suitable electrical enclosure, while the thermal overload relay is selected separately to match the motor's rated current.

Reduced-Current Starting for Industrial Motors
Star-delta starters reduce the electrical and mechanical stresses associated with starting larger three-phase induction motors. During starting, the motor windings are connected in star to reduce the voltage applied across each winding and consequently reduce starting current. Once the motor has accelerated, the starter changes the winding configuration to delta for normal full-power operation.
The Lovato BFA08070024 provides this functionality in a coordinated open-frame assembly rated for a maximum IEC operating current of 140 A. With its 24 V AC, 50/60 Hz control coils and suitability for motors up to 75 kW at 400 V, it is designed for integration into industrial motor control centres, machinery and OEM automation panels.
Typical Applications
- Industrial pumps and pumping systems.
- Fans, blowers and ventilation equipment.
- Compressors and refrigeration machinery.
- Conveyors and material handling systems.
- Processing and production machinery.
- Motor control centres and OEM automation panels.
