5. GENERAL CHARACTERISTICS
(continued):
Coordination between modular circuit-breakers, three-phase network (+ neutal) 400 / 415 V~ according to IEC/EN 60947-2:
For TT or TN neutral system in 230/400 V network, to know the breaking capacity of the combination of a double pole breaker (connected
between phase and neutral under 230 V) downstream of a triple-pole circuit-breaker, take the values shown in Tables 230/400 V.

According to the curves and ratings of circuit breakers, attention to the magnetic threshold and to the size of upstream circuit breakers which must
necessarily be higher.
