Why Choose the Lovato BF50000D024 3-Pole Power Contactor?
The Lovato BF50000D024 is a heavy-duty 3-pole power contactor designed for high-current motor switching and demanding industrial control applications. Part of the Lovato BF500 contactor series, it delivers an IEC AC-3 operational current of 500 A at voltages up to 440 V, making it suitable for large three-phase motors and high-power machinery.
At 400 V AC, the BF50000D024 is rated for an AC-3 motor power of 250 kW. It also provides a conventional free-air thermal current Ith of 700 A and an AC-1 operational current of 600 A at 40 °C, supporting demanding industrial power-control installations.
The contactor uses a DC electronically controlled coil with a rated control range of 24–48 V DC. With a 1000 V rated insulation voltage, 8 kV impulse withstand voltage, screw fixing and a mechanical life of up to 5,000,000 operations, the BF50000D024 is engineered for robust high-power switching.
