To ensure a continuous supply of electrical power, certain
installations are connected to two sources:
b a normal source N
b a replacement source R used to supply the installation when the
normal source is unavailable.
A source-changeover system switches the load between these two
sources. It can be automated to manage transfers according to
external conditions. A source-changeover system includes two or
three circuit breakers or switch-disconnectors.
With Interpact INS, Compact NS and Masterpact NT and NW, new
installation solutions are available to optimise the size of the
switchboard and simplify installation.
