Why Choose the Lovato BF42000E230 420 A 3-Pole Power Contactor?
The Lovato BF42000E230 is a heavy-duty 3-pole power contactor designed for demanding industrial motor control and power switching applications. Rated at 420 A AC-3 at up to 440 V, it provides reliable control of substantial three-phase loads and is rated for motor powers up to 200 kW at 400 V and 250 kW at 415 V.
A key feature of the BF42000E230 is its electronically controlled 100–250 V AC/DC coil. The wide control-voltage range allows the same contactor to operate from either AC or DC control supplies, helping simplify specification and inventory requirements across industrial control systems.
The BF42000E230 combines an IEC conventional free-air thermal current of 630 A, an AC-1 rating of 600 A at temperatures up to 40 °C, a 1000 V rated insulation voltage and an 8 kV impulse withstand voltage. With screw mounting, a mechanical life of 5,000,000 operations and an operating temperature range from -40 to +70 °C, it is engineered for demanding industrial switching installations.

High-Power Motor and Industrial Load Control
Power contactors allow high-current electrical loads to be controlled by a separate low-power control circuit. The Lovato BF42000E230 is specifically engineered for large industrial loads, providing an AC-3 operational current of 420 A for motor switching and an AC-1 rating of 600 A at ambient temperatures up to 40 °C for resistive and slightly inductive loads.
Its wide-range electronic coil is particularly useful in modern automation systems. The same BF42000E230 can operate from a control supply between 100 and 250 V AC or DC, providing greater flexibility when integrating the contactor into industrial machinery, motor control centres, switchboards and automated power systems.
Typical Applications
- High-power three-phase motor control.
- Industrial motor control centres and switchboards.
- Pumps, compressors and ventilation equipment.
- Industrial machinery and production equipment.
- High-current resistive and inductive load switching.
- Building services and industrial automation systems.
