BF42000E400 Lovato 3P CONTACTOR 420A AC3 250…500VAC/DC

Why Choose the Lovato BF42000E400 420 A 3-Pole Power Contactor?

The Lovato BF42000E400 is a heavy-duty 3-pole power contactor designed for demanding industrial motor control and high-current power switching applications. Rated at 420 A AC-3 at up to 440 V, it provides dependable 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 BF42000E400 is its electronically controlled 250–500 V AC/DC coil. The wide control-voltage range allows the same contactor to operate from compatible AC or DC control supplies, providing flexibility when integrating the device into industrial machinery, motor control centres and automated electrical systems.

The BF42000E400 combines a 630 A conventional free-air thermal current, an AC-1 operational current 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 environments.

High-Power Motor and Industrial Load Control

Power contactors allow high-current electrical loads to be controlled by a separate control circuit. The Lovato BF42000E400 is engineered for large industrial loads, providing an AC-3 operational current of 420 A at up to 440 V 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 industrial control systems requiring higher control voltages. The BF42000E400 can operate from a control supply between 250 and 500 V AC or DC, providing flexibility when integrating the contactor into motor control centres, switchboards, industrial machinery 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.
