Why Choose the Lovato BF63000E400 3-Pole Power Contactor?
The Lovato BF63000E400 is a heavy-duty 3-pole power contactor designed for reliable switching and control of large three-phase motors and high-current industrial electrical loads. As part of the Lovato BF630 contactor series, it provides an IEC AC-3 operational current rating of 630 A together with an electronically controlled wide-range AC/DC coil.
Designed for demanding motor-control and industrial power applications, the BF63000E400 delivers an AC-3 motor power rating of 355 kW at 400 V and an IEC conventional free-air thermal current (Ith) of 800 A. Its three normally open main poles provide dependable switching of three-phase circuits, while robust screw connections and high mechanical endurance support installation in industrial switchboards and control panels.
The electronically controlled coil operates across a broad 250–500 V AC/DC control-voltage range, allowing the contactor to be used with compatible AC or DC control supplies. With a rated insulation voltage of 1000 V, an impulse withstand voltage of 8 kV and mechanical endurance of up to 5,000,000 cycles, the BF63000E400 is engineered for demanding industrial service.
