Note: the specifications in the table is obtained as the ambient temperature of air circuit breaker is 40
℃
, with open installation; this is in
compliance with the specification of copper busbars adopted under the heating conditions regulated in IEC/EN60947-2.

Making the secondary circuit power, the motor-driven mechanism can
store energy automatically until hearing the click and energy stored
"
indicating on the panel. Otherwise press the storage handle for 6
times until hearing the click and the indicator display energy stored”
And the closing operation can be realized either by closing
electromagnet or manual button.
