Reliable High-Current Switching for Industrial Systems
Industrial contactors such as the Lovato 11B500400380 allow large motors and other high-power electrical loads to be controlled through a lower-power control circuit. This supports remote switching, automated sequencing and integration with programmable controllers, overload protection and industrial safety systems.
The four-pole B500 design is particularly suitable for installations requiring simultaneous control of multiple conductors. Its high switching capacity, robust construction and long operational life provide dependable performance in industrial motor control centres, switchboards and process machinery.
Typical Applications
- Large industrial motor starters.
- Motor control centres and electrical switchboards.
- Industrial pumps and compressors.
- Heavy conveyors and material-handling systems.
- Process manufacturing and production machinery.
- Industrial automation and high-current power-distribution panels.
