BF265T4E400 LOVATO MAXI 4P CONTACTOR 450A AC1 250-500VAC/DC

Why Choose the BF265T4E400?

Engineered for demanding installations, the Lovato BF265T4E400 four‑pole contactor delivers reliable high‑current switching. With an AC/DC coil rated 250…500VAC/DC and an IEC AC1 operating current of 450A, it suits heavy resistive duties. For motor loads at 400V (AC3), it handles 265A/132kW. Screw mounting ensures a secure fit, while compliance with IEC/EN/BS, UL and CSA standards supports safe, consistent performance in UK industrial control panels.

Built on the BF265 platform, this contactor combines robust electrical strength and endurance. It offers 1000V rated insulation (Ui) and 8kV impulse withstand, a mechanical life of 5,000,000 cycles, and dependable operation from -40 to 70°C up to 3000m altitude (pollution degree 3). These characteristics make it a dependable contactor choice for control panels and power distribution equipment where durability and safety margins matter.
