There is no price at present, you can Request a Quote
The Chint Circuit Breaker is high quality!
The rated residual inoperative current is 0.5i △ n.
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
The rated residual on and off capacity is 500a (in = 50a); 630A(In=63A)
Electrical life times (times) 2000 cos ф = 0.85 ~ 0.9 Frequent operation in > 25a, 120 times/hour
Mechanical life times (times) 20000 frequent operation in > 25a, 120 times/hour
NB1L-63 residual current operated circuit breaker is suitable for AC 50Hz, rated voltage unipolar two wires,
bipolar 230V,
In three-pole, three-pole four-wire, four-pole 400V, rated current to 63A line, when personal electric shock
or power grid leakage current exceeds
When the specified value is exceeded, the residual current operated circuit breaker can quickly cut off the
fault power supply in a very short time, protecting people and using it
The safety of electrical equipment can protect the overload or short circuit of the line, and can also be
used for infrequent conversion of the line.
This product is suitable for various places such as industry, commerce, high-rise building and civil residence.
NB1L-63 residual current operated circuit breaker is composed of NB1-63 small circuit breaker and residual current
The flow tripper is assembled and has the following characteristics:
No auxiliary power supply is needed, which overcomes the disadvantages of poor anti-interference performance of
electronic products, power grid voltage
The residual current is widened due to the defects of large fluctuation influence and unprotected neutral
line disconnection
Scope of protection.
The rated short circuit breaking capacity is high, up to 6kA.
Dynamic control of the test circuit makes it difficult to burn the test resistor.
The operating mechanism is designed as an energy storage mechanism, and the product is in moving contact
during the closing operation
The head stores energy, which makes the moving contact close quickly, and improves the service life and
product of the moving contact
The ability to break.
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.
The residual current operated circuit breaker shall, under the impact current with a peak current of 200A,
Has the bearing capacity and does not cause misoperation.
Elevation: ≤2000m
Applicable to 16mm2 and below copper wire connection with rated current In(A) 50 and cross-sectional area of
copper wire S(mm2) 10.
The rated current In(A) 63 copper conductor cross-sectional area S(mm2) 16
Wiring method: screw down the wiring with a torque of 2.0N·m .
The rated residual inoperative current is 0.5i △ n.
