BFK0910A400 - 3P CONTACTOR 7 5KVAR 400V 50/60HZ

Why Choose the BFK0910A400?

The Lovato BFK0910A400 is a contactor for power factor correction with an AC control circuit, engineered for reliable capacitor bank switching. Its 400 VAC 50/60 Hz coil and integrated limiting resistors ensure smooth inrush management, while the 7.5 kvar (400 V) rating suits compact PFC stages. A 3-pole design with a built-in 1NO auxiliary contact and screw or 35 mm DIN rail mounting simplifies fast, tidy panel integration.

Designed for resilience, the unit offers a 690 V rated insulation (Ui), 6 kV impulse withstand (Uimp) and 25 A Ith, backed by a mechanical life of 20,000,000 cycles. It operates from -50 to 70 °C up to 3000 m altitude, Pollution Degree 3. Conformity includes IEC/EN/BS 60947 and UL/CSA standards, with Sustainability certification—ideal for dependable, standards-aligned power factor correction assemblies.
