5 - Technical characteristics

Protection degree SACE Emax 2 circuit-breakers guarantee the following protection degrees:
• IP20 for circuit-breakers in fixed or withdrawable versions, excluding the terminals
• IP30 for the front parts of the circuit-breaker when it is installed in a switchboard with IP30 flange mounted
on the door
• IP54 in circuit-breakers equipped with an optional IP54 transparent flange fitted to the front door of the
switchboard.

Dissipated power To guarantee the performance of the switchgear in terms of uninterrupted rated capacity, the design of the
switchgear must take into account the power dissipated by switchgear and controlgear and by the installed
live parts. Dissipated powers are calculated according to the standard IEC 60947. The values indicated in
the table refer to the total power for each three-phase circuit-breaker with balanced loads with a current flow
equal to the rated uninterrupted current Iu. These power dissipations are measured according to the standard
IEC 60947. The values indicated in the table refer to the total power of the circuit-breakers in three-pole and
four-pole versions with balanced loads and a current flow equal to the rated uninterrupted current Iu at 50/60
Hz.
