BFK6500A400 - PFC CONTACTOR 45KVAR 400VAC 50/60HZ

Why Choose the BFK6500A400?

Lovato’s BFK6500A400 is a 3-pole contactor for power factor correction with an AC control circuit, designed to switch capacitor banks cleanly thanks to integrated limiting resistors. With 45 kvar IEC operational power at 400 V and a 400 VAC 50/60 Hz coil, the SKU BFK6500A400 delivers dependable performance and quick installation on screw fixings or 35 mm DIN rail.

Engineered for resilience, it offers 690 V rated insulation and 8 kV impulse withstand, with 100 A Ith to handle demanding duty cycles. A mechanical life of 15,000,000 operations and operation from -50 to 70 °C support long service in tough sites up to 3000 m altitude (pollution degree 3). Conformity to IEC/EN/BS 60947 and UL/CSA standards assures compatibility with industrial power factor correction systems.
