BFK1210A400 - 3P CONTACTOR 12 5KVAR 400V 50/60HZ

Why Choose the BFK1210A400?

Lovato’s BFK1210A400 is a contactor for power factor correction with an AC control circuit, engineered for reliable capacitor switching. Delivering 12.5 kvar at 400 V, it features a 400 VAC 50/60 Hz coil and built-in limiting resistors to control inrush. The 3-pole design includes a 1NO auxiliary contact and offers versatile screw or 35 mm DIN rail mounting for panel builders.

Built for demanding environments, the BFK12 platform offers Ui 690 V, Uimp 6 kV and Ith 28 A, with mechanical life to 20,000,000 cycles. Wide operating temperature from -50 to 70 °C and installation up to 3000 m support diverse sites. Conforms to IEC/EN/BS 60947-1 and 60947-4-1, plus UL and CSA equivalents, and carries a sustainability certification.
