BF33000E024 LOVATO MAXI 3P CONTACTOR 330A AC3 24-60VAC/20-60VDC

Why Choose the BF33000E024?

Lovato’s BF33000E024 is a three‑pole contactor engineered for high‑duty motor control. With an AC/DC coil rated 24…60VAC / 20…60VDC, it delivers IEC AC‑3 performance of 330A at 400V (160Kw) and 500A Ith (AC1). Rated insulation voltage is 1000 V with 8 kV impulse withstand, and screw mounting simplifies panel installation. Conforms to IEC/EN/BS, UL and CSA standards for assured compliance.

Built for reliability, the BF330 series offers 5,000,000 mechanical cycles and operates from -40 to 70 °C, up to 3000 m altitude, pollution degree 3. Terminals accept a tightening torque of 35 to 35 Nm for secure connections. UL/CSA motor rating reaches 250 HP at 480V, making it ideal for heavy conveyors, pumps and compressors in industrial panels.
