7.2 Performance requirements
7.2.1 Operating condition
7.2.1.1 Closing
For a circuit-breaker to be closed safely on to the
making current corresponding to its rated shortcircuit
making capacity, it is essential that it should
be operated with the same speed and the same
firmness as during the type test for proving the shortcircuit
making capacity
P
7.2.1.1.1 Dependent manual closing

closing mechanism, it is not possible to assign a
short-circuit making capacity rating irrespective of
the conditions of mechanical operation

Such a circuit-breaker should not be used in circuits
having a prospective peak making current exceeding
10 kA
N/A
However, this does not apply in the case of a circuitbreaker
having a dependent manual closing
mechanism and incorporating an integral fast-acting
opening release which causes the circuit-breaker to
break safely, irrespective of the speed and firmness
with which it is closed on to prospective peak
currents exceeding 10 kA; in this case, a rated shortcircuit
making capacity can be assigned
N/A

closing mechanism can be assigned a short-circuit
