CHINT LMI-B1 Mechanical Interlock,
ensures safe manual switching between two main power sources.
It prevents simultaneous operation of dual circuits by mechanically interlocking connecte breakers.
on the other hand it is Designe for use in residential, commercial,
and industrial installations—such as homes, hotels, offices, and shopping centers—the LMI-B1 offers reliable, compact,
furthermore easy-to-install protection. With a 9 mm width, wide temperature range (–35°C to +70°C),
finally DIN-rail compatibility, it is ideal for low-voltage dual-supply systems.
