Residual current protection type AC type
Number of poles 1P+N, 2P, 3P, 3P+N, 4P
Type c of instantaneous release
The rated short-circuit breaking capacity is 6000A(NB1LE-40) and 10000A(NB1LE-40H)
The rated residual on and off capacity is 500A
Tightening torque 2.0N? m
Pollution level 2
Protection grade IP20
Electrical life times (times) 2000 cos ф = 0.85 ~ 0.9 operating frequency In≤25A, 240 times/hour; In > 25a, 120 times/hour
Mechanical life times (times) 20000 operating frequency In≤25A, 240 times/hour; In > 25a, 120 times/hour
The NB1LE-40□ residual current operated circuit breaker is suitable for AC 50Hz, rated voltage unipolar
two-wire and bipolar 230V.
Three-pole, three-pole four-wire, four-pole 400V, rated current to 40A line, when personal electric shock
or grid leakage current exceeds
When the value is specified, the residual current operated circuit breaker can quickly cut off the fault
power supply in a very short time to protect people and electricity
The safety of equipment can protect the overload or short circuit of the line, and can also be used for
infrequent conversion of the line.
Products are suitable for industrial, commercial, high-rise buildings and residential buildings.
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. The peak value between each pole and the neutral pole and the metal bracket is 8000V V.
Impulse voltage.
Under the action of impulse current with peak current of 200A, residual current operated circuit breaker has
Bearing capacity, and does not cause misoperation.
Elevation: ≤2000m.
