load break switches: what are they for?
Load break switches are devices used to open an electrical circuit
by isolating the source from the consumer. Whether they are manual,
motorised or with a trip function, these devices ensure the on-load
making, breaking and safety disconnection of low-voltage electrical
circuits. Easy to assemble and easy to use, they are suitable for
structures evolving in the industrial sector, public distribution,
as well as emergency switching, distribution panels and motor
feeders.
