4.9.9.1 Description
General
Plastic enclosures for surface mounting and molded-plastic enclosures for flush mounting
are available in various dimensions for the stand-alone assembly of size S00 (I
n max
= 16 A)
and S0 (I
n max
= 32 A) motor starter protectors.
In the case of installation in molded-plastic enclosures the rated operational voltage U
e
of the
motor starter protectors is 500 V.
The enclosures for surface mounting have IP55 degree of protection and those for flush
mounting also meet the requirements for IP55 degree of protection at the front (the flush-
mounted section complies with IP20).
Enclosures
All enclosures are equipped with N and PE terminals. They have 2 knockout cable entry
openings for cable glands at the top and 2 at the bottom, along with corresponding cable
entries scored on the rear. There is a knockout on the top of the enclosure for indicator lights
which are available as accessories.
The slim-line enclosure can accommodate a motor starter protector without accessories, with
transverse and lateral auxiliary switches. There is no provision for installing a motor starter
protector with signaling switch.
In the case of size S00 and S0 motor starter protectors, the molded-plastic enclosures are
fitted with a rotary operating mechanism.
The enclosures are available either with a black rotary operating mechanism or with an
EMERGENCY STOP rotary operating mechanism with red/yellow handle.
In the OFF setting, all rotary operating mechanisms can be locked with up to three padlocks.
Front plates
Many applications require motor starter protectors to be actuated in any type of enclosure.
Front plates equipped with a rotary operating mechanism are available for size S00 and S0
motor starter protectors for this purpose.
A holder for size S00 and S0 motor starter protectors is available for the front plates (the
motor starter protectors snap into the holder).
