Why Choose the Lovato BF500T4E400 4-Pole Power Contactor?
The Lovato BF500T4E400 is a heavy-duty 4-pole power contactor designed for high-current industrial load switching. Part of the Lovato BF500 contactor series, it has a conventional free-air thermal current Ith of 700 A and four normally open main power contacts, making it suitable for demanding power distribution, resistive-load and industrial control applications.
For AC-1 duty, the BF500T4E400 provides a rated operational current of 600 A at temperatures up to 40 °C, with ratings of 590 A at 55 °C and 510 A at 70 °C. The contactor also provides 500 A AC-3 performance at up to 440 V and is rated for three-phase motors up to 250 kW at 400 V.
An electronically controlled 250–500 V AC/DC wide-range coil allows operation from compatible AC or DC control supplies. Combined with a 1000 V rated insulation voltage, 8 kV impulse withstand voltage and robust screw mounting, the BF500T4E400 provides a dependable switching solution for demanding industrial installations.
