(continued)
Association and coordination with upstream Moulded Case Circuit Breakers (MCCBs), only for sensitivities 300mA and
1000mA:
. Three-phase network (+N) 230/240 V, in accordance with standard IEC 60947-2
. TT neutral earthing or TNS system

Selectivity between two levels of protection
. The downstream MCB must always have a magnetic threshold and a rated current lower than those of the upstream protection.
. Selectivity or Discrimination is said to be total (T) if there is discrimination up to the value of breaking capacity (in accordance with standard
EN/IEC 60947-2) of the downstream MCB.
Discrimination with upstream fuses, only for sensitivities 300mA and 1000mA:
. Discrimination limit with a voltage of 230 V ~ (Values in A)
