Why Choose the BF0901A400?
The Lovato BF0901A400 is a robust three‑pole contactor designed for reliable motor and load switching. With an AC coil rated 400 VAC, 50/60 Hz, and an IEC AC‑3 current of 9 A at 400 V, it delivers dependable performance. A built‑in 1NC auxiliary contact provides mirror contact function, while screw or 35 mm DIN rail mounting simplifies installation in control panels.
Engineered for endurance, it offers 25 A AC‑1, 690 V rated insulation and 6 kV impulse withstand, with a mechanical life of 20,000,000 cycles. Operating from −50 to 70 °C and up to 3000 m altitude, it carries UL/CSA horsepower ratings (5 HP at 480 V) and conforms to IEC/EN/BS 60947 standards, suiting demanding British industrial environments.
