BFK3800A110 - 3P CONTACTOR 30KVAR 110V 50/60HZ

Why Choose the BFK3800A110?

Designed for dependable capacitor bank switching, the Lovato BFK3800A110 is a contactor for power factor correction with an AC control circuit. Rated 30kvar at 400V, this 3‑pole unit uses a 110VAC 50/60Hz coil and includes limiting resistors for reduced inrush. Flexible screw or 35mm DIN rail mounting supports rapid panel integration.

Built to international standards, the BFK38 series offers Ui 690V, Uimp 6kV and Ith 56A for robust performance. A mechanical life of 20,000,000 cycles and an operating range from -50 to 70°C suit demanding environments up to 3000 m altitude. Conforms to IEC/EN/BS 60947-1/-4-1, UL and CSA requirements for assured compliance.
