First, the scope

DZ47LE-63 series leakage circuit breakers from the DZ47 MCB and leakage release assembly formed. The product is suitable for AC 50Hz, rated working voltage 230V ~ 400V, rated current up to 100A of circuit, mainly by the zero-sequence current transformer, electronic component board, leakage circuit breakers with overload and short circuit protection, also based on user We need to increase the overvoltage, undervoltage protection for indirect contact protection for people, as well as line buildings and similar uses overcurrent protection. Also provides protection against fire due to an overcurrent protection device does not operate and the persistence of a ground failure. Leakage circuit breakers with overvoltage protection but also on the voltage due to the power failure caused by excessive protection.
DZ47LE leakage circuit breakers in the low-voltage distribution system has been more and more It is employed as a ground fault and direct contact, indirect contact shock of backup protection. The products are mainly used in building illumination and power distribution systems, in line with GB16917.1 and IEC61009-1 standards. Our company has passed the national CCC, CE certification.

Second, model and specification

Third, the structural characteristics

DZ47LE leakage circuit breakers is integrated by the leakage release and DZ47 circuit breaker attachment assembly formed, thus maintaining the same time DZ47 - current operating characteristics, mechanical assembly, it can be completed by the enterprises in the factory, also available on-site. Leakage tripping characteristic parameters from the factory setting, the user can not adjust, we can not open the leakage release, so as not to affect performance. Leakage release 32A and 50A have two kinds of frame degree current, respectively, can be accessed 10mm? and 25mm? wire.
On the leakage release features a special operation to indicate leakage indicating device, indicating device reset only after, leakage circuit breaker to close. And with a band of self-test device Duplex button, when pressed inside line to produce an analog residual current circuit breaker breaking. Test equipment should be regularly tested once a month.  

Fourth, the normal working conditions and installation conditions

◆ ambient air temperature is minus five degrees to forty degrees Celsius, an average of no more than thirty twenty-four hours five degrees Celsius.
◆ Altitude: the installation site altitude does not exceed 2000m.
◆ atmospheric conditions: air installation location relative humidity at the highest temperature of forty degrees Celsius does not exceed fifty percent, at a lower temperature allows a greater relative humidity; for example up to ninety percent twenty-five degrees Celsius .
◆ Installation category: II, III level.
◆ Pollution degree: 2.
◆ Mounting: use TH35-7 steel mounting rail installation.
◆ Installation conditions: external magnetic field in any direction installation site should not exceed 5 times the earth's magnetic field; RCBO general should be mounted vertically, the handle for the power-up position; installation should be no significant impact and vibration.
◆ Connection: Screw-wiring.
