A product of outstanding quality, the current family
of panelboard designs represents the high level of
engineering innovation expected from Siemens.
Additional strength has been added to an already
rugged and durable panelboard family. At the same time,
many models have a trimmed exterior size, have added
flexibility and are easier to install. These newer designs
simplify wiring and reduce material requirements, saving
additional installation time.
The lighting panel design still features the Fas-Latch
trim that is so popular with installers, the jacking screw
system that permits adjustments even after wiring has
been installed, and other features such as exclusive split
neutral. Many panelboards have the capability of mixing
and matching breakers of different sizes and ratings, or
changing from main lug to main breaker, or adding sub-
feed breakers without changing box size.
The complete family of panelboards from Siemens
employs numerous features – all industry-leading, many
exclusive. Note the following, all found in the innovative
