Why Choose the BFK1810A048?
The Lovato BFK1810A048 is a contactor for power factor correction with an AC control circuit, designed for reliable capacitor switching. Featuring built-in limiting resistors and a 48 VAC 50/60 Hz coil, this 3-pole unit delivers 15 kvar at 400 V. With 1NO auxiliary contacts and flexible screw or 35 mm DIN rail mounting, the BFK1810A048 streamlines installation in new builds and upgrades.
Robustly engineered to IEC/EN/BS 60947-1 and 60947-4-1, the BFK18 series offers a 690 V insulation rating and 6 kV impulse withstand, with Ith 32 A for dependable service. A mechanical life of 20,000,000 cycles and an operating range from -50 to 70 °C ensure longevity, while pollution degree 3 and operation up to 3000 m suit demanding UK installations.
