BFK2600A400 - 3P CONTACTOR 20KVAR 400V 50/60HZ

Why Choose the BFK2600A400?

Lovato’s BFK2600A400 is a contactor for power factor correction with AC control circuit, supplied with limiting resistors for reliable capacitor switching. Delivering up to 20 kvar at 400V, this 3‑pole device employs a 400VAC 50/60Hz coil and supports screw mounting or 35mm DIN rail installation. Part of the BFK26 family, it helps stabilise reactive power in low-voltage systems while maintaining straightforward integration into control panels and capacitor bank assemblies.

Engineered for durability, it offers rated insulation voltage Ui 690 V, impulse withstand Uimp 6 kV and Ith 45 A, with mechanical life to 20,000,000 cycles. A wide -50 to 70 °C operating range and pollution degree 3 suit demanding sites up to 3000 m altitude. Installation is simple with 2.5–3 Nm terminal torque, and compliance covers IEC/EN/BS 60947-1/-4-1 plus UL and CSA standards.
