• 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
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.
