Tightening torque 2.0N? m
Electrical life times (times) 2000 cos ф = 0.85 ~ 0.9 Operating frequency in > 25a, 120 times/hour
Mechanical life times (times) 20000 operating frequency in > 25a, 120 times/hour
NB1LE-63□ Residual current operated circuit breaker is suitable for AC 50Hz, rated voltage unipolar
two-wire, bipolar
230V, three-pole, three-pole four-wire, four-pole 400V, rated current to 63A. When people get electric
shock or the power grid leaks,
When the current exceeds the specified value, the residual current operated circuit breaker can
automatically cut off the power supply in a very short time to ensure personal safety
And prevent equipment accidents caused by leakage current.
Residual current operated circuit breakers also have overload and short circuit protection functions,
which can be used to protect the overload and short circuit of lines.
It can also be used for infrequent line switching under normal conditions.
Impulse voltage resistance of insulation:
A. the impulse voltage with a peak value of 6000V can be borne between the poles connected together and the neutral pole;
B. each pole is connected with the neutral pole and can bear the impulse voltage with the peak value of 8000V between the pole and the metal bracket.
The residual current operated circuit breaker can withstand the impact current with a peak current of 200A, and does not cause misoperation.
Elevation: ≤2000m.
