Installation positions
The circuit-breaker can be installed in any position without any
effect on its rated characteristics. In compliance with the IEC
60947-2 Standards, SACE Isomax S circuit-breakers can be
supplied through either top or bottom terminals, without jeopardising
operation of the apparatus.
They can be installed in switchboards, mounted directly on the
base plate or on Din rails up to size S5.

Mounting on DIN rail up to 630 A
The brackets for fixing onto standardised DIN EN 50022 rails
for S1, S2 and DIN EN 50023 rails for S3, S4, S5 simplify assembly
of the circuit-breakers up to 630 A in standard switchboards.
This allows standardised supporting structures to be used and
facilitates the stage for designing and constructing the switchboard
metalwork structure.

Resistance to vibration
Degrees of protection
The circuit-breakers are unaffected by vibrations generated
mechanically or due to electromagnetic effects, in compliance
with the IEC 68-2-6 Standards and the strictest regulations of
the major classification organisations:
– RINA
– DET Norske Veritas
– Lloyd’s Register of Shipping
– Germanischer Lloyd
– Bureau Veritas.
Different measures have been taken in SACE Isomax S circuitbreakers
to achieve IP20 degree of protection for the fixed,
plug-in and withdrawable version circuit-breaker, excluding
the terminals, and IP30 for the front parts of the circuit-breakers
installed in switchboards.
The fixed parts are always provided with IP20 degree of protection.
It is possible to achieve IP54 degree of protection in accordance
with the IEC 60529 Standard with the circuit-breaker
installed in a switchboard fitted with rotary handle operating
mechanism transmission on the compartment door and the
special insulation gaskets which can be ordered separately.
