63A Residual Current Operated Circuit Breaker RCB MCB Circuit
Breaker Heat Resistant
Application
The DZ47LE residual current operated circuit breaker is applicable
to the circuit with an alternating current of 50Hz, rated-voltage
single pole and two lines/two poles 230V, three poles/three poles
and four lines/four poles 400V, and a rated current up to 63A; when
the human body gets an electric shock or thenetworkleakcurrent
exceeds the specified value, the residual current operated circuit
breaker can rapidly cut off the power supply in trouble within a
very short time for the safety of the human body and the powered
equipment. With the function of overload and short circuit
protection, the residual current operated circuit breaker can be
used to protect the circuit or motor from being damaged by overload
and short circuit, and can also be used for not–frequent
operational transformation in the circuit under normal
condition.The product meets the standards of IEC 61009-1.
Normal operating conditions:
1. air temperature: -5°C~+40°C, the mean value is no higher than
+35°C within 24 hours .
2. Altitude: not higher than 2000m in installation site.
3. Atmospheric conditions:The air Relative humidity in the
installation point will can't more than 50% in the highest
temperature 40 C.
The air Relative humidity can't more than 90%, in the month most
humidity and Monthly average minimum temperature not higher than 25
C.
4. Installation category: II, III grade.
5. Pollution degree: 2 grade.
6. Installation: Standard rail installation TH35-7.5 DIN rail
7. Installation conditions: Installation place of the external
magnetic field in any direction should not exceed 5 times of the
geomagnetic field, leakage
circuit breaker shall be installed vertically, generally handle up
to position, turning on the power supply installation area should
be no significant impact
and vibration.
8. Connection: screw wiring.

Circuit breakers perform 3 key functions: protection, switching,
and monitoring. Circuit breakers are designed to “break”
(discontinue) the flow of electricity to protect people and
equipment when current reaches an unsafe level due to overload,
short circuit, or other electrical faults. We are your one source
solution for all your circuit breaker and equipment needs.
Normally, we will provide the most suitable shipment method for
you. If the quantity is few, the goods will be sent by express when
the payment is clear. Also, we can transport the goods by air or by
sea, just according to your demand
