BF33000E400 LOVATO MAXI 3P CONTACTOR 330A AC3 250-500VAC/DC

Why Choose the BF33000E400?

Designed for heavy-duty motor switching, the Lovato BF33000E400 three‑pole contactor delivers dependable performance in demanding industrial panels. With an AC/DC coil rated 250…500 V and AC‑3 current of 330 A at 400 V (160 kW), it handles high loads with confidence. Robust insulation to 1000 V and 8 kV impulse withstand enhance reliability across applications requiring secure, efficient power control.

Built for longevity, the BF330 series boasts 5,000,000 mechanical cycles, operating from -40 to 70 °C and up to 3000 m altitude. Screw mounting simplifies secure installation, while UL/CSA 250 HP at 480 V underscores high-capacity operation. Conforming to IEC/EN/BS 60947-1 and 60947-4-1, it suits harsh environments (pollution degree 3) where consistent, high-current motor control is essential.
