BF series contactors

The Lovato BF series contactors are engineered for robust motor control applications, offering a wide range of current ratings from 9A to 630A in AC-3 duty. Available in both 3- and 4-pole configurations, these contactors are designed to handle demanding industrial environments. The BF series supports various coil voltage options, including AC, DC, and low-consumption DC coils, ensuring compatibility with diverse control systems.

Key features of the BF series include positively guided contacts for enhanced safety, built-in surge suppressors in models up to 150A, and the ability to mount up to eight auxiliary contacts for increased functionality. The contactors are equipped with electronic coils that offer a wide operating voltage range and reduced power consumption, contributing to energy efficiency. These attributes make the BF series suitable for applications such as motor starters, power factor correction, and integration into complex automation systems.
