BFK1210A048 - 3P CONTACTOR 12 5KVAR 48V 50/60HZ

Why Choose the BFK1210A048?

Designed for reliable capacitor switching, the Lovato BFK1210A048 is a contactor for power factor correction with an AC control circuit. It incorporates limiting resistors and delivers up to 12.5kvar at 400V. A 48VAC 50/60Hz coil, three-pole configuration and a built‑in 1NO auxiliary contact make this unit a compact, dependable choice for low‑voltage power factor correction panels and control systems.

Engineered for demanding environments, the BFK12 series contactor offers Ui 690 V, Uimp 6 kV and Ith 28 A, with a mechanical life of 20,000,000 cycles. It operates from -50 to 70 °C up to 3000 m and mounts via screws or 35 mm DIN rail. Conforms to IEC/EN/BS 60947-1 and -4-1, plus UL and CSA equivalents.
