BFK8000A024 - PFC CONTACTOR 50KVAR 24VAC 50/60HZ

Why Choose the BFK8000A024?

The Lovato BFK8000A024 contactor for power factor correction with AC control circuit is built for reliable switching of three-phase capacitor banks. Featuring integrated limiting resistors and a 24 VAC 50/60 Hz coil, this 3-pole unit delivers 50 kvar at 400 V. With Ui 690 V and Uimp 8 kV, the BFK80 series mounts via screw fixing or 35 mm DIN rail for straightforward panel assembly.

Designed for longevity and harsh environments, it offers 15,000,000 mechanical cycles and Ith 115 A, operating from -50 to 70 °C and up to 3000 m altitude. Conformity with IEC/EN/BS 60947-1 and 60947-4-1, plus UL and CSA equivalents, ensures assured performance in UK and global panels. Terminal torque is 4 to 5 Nm for secure terminations.
