£3,450.51
The Lovato 11B5000048 is a heavy-duty three-pole industrial power contactor designed for reliable switching of large three-phase motors and high-current electrical loads. As part of the robust Lovato B500 contactor series, it combines a high switching capacity with a versatile 48 V AC/DC control coil for integration into industrial automation and motor-control systems.
Engineered for demanding operating environments, the contactor offers dependable electrical performance, high mechanical endurance and secure screw mounting. Its three normally open main poles and heavy-duty power terminals make it suitable for motor control centres, switchgear assemblies, OEM machinery and industrial power-control panels.
With a conventional free-air thermal current rating of 700 A and an IEC AC-3 operational rating of 520 A / 290 kW at 400 V, the Lovato 11B5000048 provides the capacity required for controlling large pumps, compressors, conveyors and process machinery.
Industrial contactors such as the Lovato 11B5000048 allow large motors and high-power electrical equipment to be controlled through a lower-power control circuit. This supports remote switching, automated sequencing and integration with programmable controllers, overload relays and industrial safety systems.
The B500 contactor’s high current capacity, robust construction and broad operating-temperature range make it suitable for intensive industrial applications where reliable switching and long-term operational stability are essential.
