Why Choose the Lovato BF63000E110 3-Pole Power Contactor?
The Lovato BF63000E110 is a heavy-duty 3-pole power contactor designed for high-current industrial motor control and power switching applications. Part of the advanced Lovato BF630 contactor series, it provides an IEC AC-3 operational current rating of 630 A and is engineered for controlling large three-phase motors in demanding machinery, process and automation installations.
The BF63000E110 incorporates an electronically controlled wide-range coil that can be powered from either AC or DC supplies across 60–130 V AC/DC. This flexible coil design simplifies integration with different industrial control architectures while providing dependable contactor operation. Its three normally open main power contacts are designed for high-current switching, with an IEC conventional free-air thermal current of 800 A.
For three-phase motor applications, the BF63000E110 is rated at 355 kW at 400 V AC under AC-3 duty and maintains a 630 A AC-3 current rating at 230–440 V. A 1000 V rated insulation voltage, 8 kV impulse withstand voltage, high short-time current capability and robust screw-mounted construction make it suitable for high-power motor control centres and industrial electrical installations.

Reliable High-Power Motor Control for Industrial Automation
Power contactors such as the Lovato BF63000E110 allow large three-phase motors and other high-current electrical loads to be switched remotely through industrial control systems. Energising the electronically controlled coil closes the three main power contacts, enabling high-power equipment to be started and stopped without routing the motor current through low-power switches, PLC outputs or control devices.
The BF63000E110 is engineered for demanding high-power applications, providing a 630 A AC-3 operational current and a motor rating of 355 kW at 400 V AC. Its wide-range 60–130 V AC/DC coil, robust electrical insulation and high switching capacity make it particularly suitable for motor control centres, heavy machinery and automated industrial installations.
