BFK3800A230 - 3P CONTACTOR 30KVAR 230V 50/60HZ

Why Choose the BFK3800A230?

Lovato's BFK3800A230 contactor for power factor correction with an AC control circuit is engineered for dependable capacitor switching in low-voltage systems. Integrating limiting resistors and a 230VAC 50/60Hz coil, it delivers up to 30kvar at 400V across three poles. With versatile screw or 35mm DIN-rail mounting, the BFK3800A230 suits space-conscious control panels, upgrades, and new builds where efficient power factor management is essential.

Built to last and perform, this BFK38 series unit offers Ui 690 V and Uimp 6 kV, with Ith 56 A for demanding duty. A 20,000,000-cycle mechanical life, Pollution Degree 3 rating, and operation from -50 to 70 °C provide resilience. It also meets IEC/EN/BS 60947-1/-4-1, UL 60947-1/-4-1 and CSA C22.2 requirements for assured compliance.
