BFK5000A230 - PFC CONTACTOR 40KVAR 230VAC 50/60HZ

Why Choose the BFK5000A230?

Lovato’s BFK5000A230 is a contactor for power factor correction with AC control circuit, engineered for dependable capacitor switching. With a 230VAC 50/60Hz coil and 3‑pole configuration, it delivers up to 40 kvar at 400V per IEC ratings. Integrated limiting resistors support smooth engagement and reduced stress on capacitor banks, helping ensure consistent operation in reactive power compensation applications.

Built for demanding environments, it offers Ui 690 V, Uimp 8 kV and Ith 90 A, with a mechanical life of 15,000,000 cycles. Operating from -50 to 70 °C up to 3000 m altitude, it mounts via screws or 35 mm DIN rail. Conformity with IEC/EN/BS 60947-1/-4-1, UL and CSA standards supports safe, reliable performance in industrial and commercial PFC systems.
