Why Choose the Lovato BFA08070110 Star-Delta Starter?
The Lovato BFA08070110 is a complete open-frame star-delta motor starter designed for reduced-current 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 demanding motor starting applications.
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 switching them to delta for normal operation. The BFA08070110 provides a coordinated contactor assembly for this starting method, helping simplify the construction of industrial motor control panels while reducing electrical and mechanical stress during starting.
The BFA08070110 uses 110 V AC, 50/60 Hz contactor coils and is designed for starting times up to 12 seconds with a maximum operating frequency of 30 operations per hour. Its open-frame construction is intended for installation inside a suitable electrical enclosure, with the motor overload relay selected separately according to the motor and application requirements.

Reduced-Current Starting for Industrial Motors
Star-delta starters control the starting sequence of compatible three-phase motors by initially connecting the motor windings in star. This reduces the voltage applied across each winding and consequently reduces starting current and starting torque. Once the motor has accelerated, the starter changes the winding configuration to delta for normal running operation.
The Lovato BFA08070110 provides this functionality in a coordinated open-frame assembly with a maximum IEC operating current of 140 A. Its 110 V AC, 50/60 Hz control coils make it suitable for industrial installations using this control voltage, while the coordinated starter format helps simplify integration into motor control centres, machinery and OEM automation panels.
