Presentation
Decisions concerning the Form of separation and the
degree of protection are the subject of an agreement
between the manufacturer and the user.
In most installations, Prisma Plus cubicles do not require partitioning. In this case,
the switchboard is a Form 1.
Safety being one of its foremost goals, Schneider Electric offers options and features
that go well beyond the recommendations of the standard.
The protection of life and property is a standard feature due to:
front plates that require a tool to be removed
keylocks on doors, some of which provide access to live parts
the systematic installation of terminal shields on Compact NSX circuit breakers
and Interpact INS and INV switch-disconnectors
covering of the upstream and downstream terminals on the incoming device so
that operators are perfectly safe at all points in the switchboard when the incoming
device is off (open).
What is more, Prisma Plus offers different levels of partitioning to create separations
inside the cubicles and thus create Form 2, 3 and 4 electrical switchboards.
Electrical switchboards must meet the degree of protection IP2X to comply with
standard IEC 60439-1.
