Why Choose the Lovato BF50000E110 3-Pole Power Contactor?
The Lovato BF50000E110 is a heavy-duty 3-pole power contactor engineered for high-current motor switching and demanding industrial control applications. Part of the Lovato BF500 contactor series, it provides 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 BF50000E110 is rated for an AC-3 motor power of 250 kW. It also provides a conventional free-air thermal current Ith of 700 A, giving the contactor substantial capacity for industrial power switching and motor-control installations.
The BF50000E110 incorporates an electronically controlled wide-range 60–130 V AC/DC coil, allowing the same contactor to operate from compatible AC or DC control supplies. A 1000 V rated insulation voltage, 8 kV impulse withstand voltage and mechanical durability of up to 5,000,000 operations support reliable service in demanding industrial environments.
