Why Choose the Lovato 11B6304SL00220 Power Contactor?
The Lovato 11B6304SL00220 is a heavy-duty four-pole power contactor designed for reliable switching of high-current electrical loads in industrial control, automation and power distribution systems. As part of the proven Lovato B630 contactor series, it combines high current capability with an AC/DC coil and preparation for optional mechanical latching using the G495 accessory.
This contactor provides an IEC conventional free-air thermal current rating of 800 A in AC-1 duty and an AC-3 operational rating of 630 A / 355 kW at 400 V, making it suitable for large industrial motors, electrical distribution systems and high-power switching applications. Its four normally open main poles enable reliable switching of four conductors in demanding installations.
The integrated 220–240 V AC/DC coil provides flexible compatibility with modern industrial control systems. The contactor is predisposed for the G495 mechanical latch, allowing future expansion where maintained contact positioning is required.
