The LOVATO Electric 11B31040060 is a heavy-duty four-pole industrial power contactor engineered for reliable switching of high-current electrical loads. As part of the robust LOVATO B310 contactor series, it offers a conventional free-air thermal current rating of 450 A (AC-1) and an operational current of 320 A (AC-3), making it ideal for industrial motor control, power distribution and demanding automation systems.
Equipped with a versatile 60 V AC/DC control coil, this contactor can be integrated into both alternating-current and direct-current control circuits. Its four-pole configuration enables simultaneous switching of four conductors, making it particularly suitable for applications requiring neutral switching or complete isolation of three-phase circuits.
Designed for dependable long-term operation, the 11B31040060 combines a robust screw-mounted construction, high insulation performance and compliance with international IEC, UL and CSA standards, ensuring reliable operation in industrial control panels, switchboards and OEM machinery.
Four-pole contactors provide safe switching of high-current electrical circuits using a low-power control signal. They enable PLCs, relays, pushbuttons and automation controllers to operate industrial loads while maintaining electrical isolation between the control and power circuits.
The LOVATO B310 series is designed for demanding industrial environments where high current capacity, dependable switching and long service life are essential. Its four-pole configuration makes it ideal for power distribution, neutral switching and heavy-duty motor control applications.
