15.1 Under-voltage release
a.Without power supply, under-voltage release can't close.
b.It is classified into instantaneous and time-delay type.
c.Delay time 0,1s,2s,3s,4s,5s,6s,7s are fixed for NA1-1000, 1s,3s,5s7s are fixed for NA1-2000,3200,4000,6300.
d.Within 1/2 time-delay range, circuit breaker does not trip when power voltage recovers and exceeds 85%Ue.
e.Characteristic
Close the circuit breaker before operation the circuit breaker.
