Why Choose the Lovato BFL23000B230 Magnetically Latched Contactor?
The Lovato BFL23000B230 is a high-performance three-pole magnetically latched power contactor designed for industrial switching applications where the contactor must remain closed for extended periods without continuous coil energisation. As part of the Lovato BF contactor family, it combines high current capability with a magnetic latching mechanism that reduces energy consumption and improves resilience to supply voltage dips.
Unlike a conventional contactor that requires continuous coil power to remain energised, the BFL23000B230 uses separate closing and opening windings that require only a short control pulse. An internal permanent magnet then holds the contactor in its commanded position without ongoing coil power, making it particularly suitable for installations where prolonged contact closure, reduced control-circuit consumption and dependable switching are important.
With a conventional thermal current rating of 350 A AC-1, an operational current of 230 A AC-3 and a motor switching capability of 110 kW at 400 V AC, the BFL23000B230 is engineered for demanding industrial loads. Its 230 V AC/DC control voltage provides flexible integration into AC or DC control systems.

Energy-Efficient Magnetic Latching for Industrial Switching
Magnetically latched contactors such as the Lovato BFL23000B230 use a permanent magnetic holding system rather than requiring continuous electrical power to maintain the closed position. Separate closing and opening coils receive short electrical pulses to change the contact state, after which the internal magnet maintains the selected position.
This operating principle can significantly reduce control-circuit energy consumption in applications where the contactor remains closed for long periods. It also helps maintain the contactor state through temporary control-voltage dips, making the BFL23000B230 well suited to industrial distribution, motor control and automation systems requiring reliable long-duration switching.
Typical Applications
- Industrial motor control and switching systems.
- High-power machinery and production equipment.
- Industrial electrical distribution panels.
- Loads requiring prolonged contactor closure.
- Energy-management and load-control systems.
- Pumps, compressors and ventilation equipment.
- Automated production and process-control installations.
- Applications requiring reduced contactor coil energy consumption.
