8.3.5 TEST SEQUENCE III (Icu)
EasyPact CVS630F, electronic type, 3 poles, 630 A
Rated ultimate short-circuit breaking
Except where the combined test sequence applies, this test sequence applies to
circuit-breaker of utilization category A and to circuit-breaker of utilization B having a
rated ultimate short-circuit breaking capacity higher than the rated short-time
withstand current.
For circuit-breakers of utilization B having a rated short-time withstand current equal
to their rated ultimate short-circuit breaking capacity, this test sequence need not be
made, since, in this case, the ultimate short-circuit breaking capacity, is verified when
carrying out test sequence IV.
For integrally fused circuit-breakers, test sequence V applies in place of this
sequence.
