BFK1810A110 - 3P CONTACTOR 15KVAR 110V 50/60HZ

Why Choose the BFK1810A110?

Lovato BFK1810A110 is a contactor for power factor correction with an AC control circuit, designed for dependable capacitor bank switching. It integrates limiting resistors to curb inrush and uses a 110 VAC 50/60 Hz coil for straightforward control integration. The 3-pole device delivers 15 kvar at 400 V and includes a 1NO auxiliary contact. Convenient screw or 35 mm DIN rail mounting speeds panel building and retrofits.

Built for demanding environments, the BFK18 series offers 690 V rated insulation and 6 kV impulse withstand, with Ith 32 A for robust performance. Mechanical life reaches 20,000,000 cycles, and operation is specified from -50 to 70 °C up to 3000 m altitude. Conforms to IEC/EN/BS 60947-1 and 60947-4-1, UL 60947-1/-4-1, and CSA C22.2 n° 60947-1/-4-1 for assured compliance.
