BFK15000A400 - CONTACTOR FOR PFC 100KVAR 400VAC 50/60HZ

Why Choose the BFK15000A400?

Lovato’s BFK15000A400 is a contactor for power factor correction with AC control circuit, engineered for reliable capacitor switching. This 3‑pole BFK150 series unit delivers up to 100 kvar at 400 V and features a 400 VAC 50/60 Hz coil with integrated limiting resistors to curb inrush. Flexible screw or 35 mm DIN rail mounting streamlines installation in low‑voltage panels.

Built for demanding environments, it offers Ui 690 V, Uimp 8 kV and Ith 165 A, with a mechanical life of 15,000,000 cycles. Operates from −50 to 70 °C up to 3000 m altitude, pollution degree 3. Conforms to IEC/EN/BS 60947-1 and 60947-4-1, plus UL and CSA equivalents, and supports sustainability‑focused procurement.
