DZ47LE 32 Leakage Circuit Breaker N connection live wire or neutral wire

1:n to the neutral line.

2:C is a model of circuit breaker, which is used for lighting circuits, and cannot be used for inductive loads, such as electric motors. For resistive loads such as:

Lighting, electric heating appliances. 25 and 16 represent the maximum load current of this model is 25 amps or 16 amps, and if the load current exceeds this value, the circuit breaker will be automatically disconnected.

DZ47 is empty on, DZ47LE is leakage.

C16 is for 16a and C25 for 25a.

n, of course, is connected to the neutral line.

From left to right, the top is U, V, and W at one time, i.e., three phases.

I don't know if you're satisfied?

Leakage circuit breaker is a switch that can automatically operate when the leakage current in the circuit exceeds a predetermined value. Commonly used leakage circuit breakers are divided into two types: voltage type and current type, and current type is divided into electromagnetic type and electronic type. Leakage circuit breakers are used to prevent electric shock to people, and should be selected according to the different requirements of direct contact and indirect contact protection.

C16 rated current 16A

C25 rated current 25A

n to the neutral line.

n indicates the neutral line and l indicates the live wire.

C16 indicates a rated current of 16A

C25 indicates a rated current of 25A

n to the neutral line. C16,25 is the rated current.

The protected loop power lines, including phase and neutral, should be threaded into the zero-sequence current transformer. A section of power cord threaded into the zero-sequence transformer should be tightly wrapped with insulating tape, bundled into a bundle and threaded through the center of the zero-sequence current transformer hole, the purpose of which is to eliminate the unbalanced magnetic flux generated in the core due to the asymmetrical position of the wire.

Note that the zero line drawn from the zero sequence transformer cannot be repeatedly grounded, otherwise when the three-phase load is unbalanced, the unbalanced current will be generated, and all will not return from the zero line, and only a part will return from the bottom. Therefore, the vector sum of the current through the zero sequence current transformer cannot be zero, and when the secondary coil has an output, it may cause wrong operation.

A and B are power incoming lines: A needs to be connected to the live wire (L phase); b to connect the zero line (n phase);

The two holes on the left side of the lower end are the wiring points that are assembled with the leakage module, so you can not move it; The C and D on the right are the outlet, the same left is the live line, and the right is the neutral outlet.

The DZ47LE series is an electronic residual current circuit breaker.

The wiring method of A1 in B1 and A2 in B2 is correct.

You can change a circuit breaker, if it still trips, it is likely that there is a leakage current in the line that is greater than the rated residual operating current. Otherwise, it is a circuit breaker failure.

The neutral line and equipotential grounding wire of your home may be interconnected, check the wiring, and the action of the leakage protection must be problematic.

The DZ47LE-63 you are talking about is called the electromagnetic residual current circuit breaker, which can play a leakage protection, should be installed in accordance with the wiring diagram of the switch superscript, live wire, zero line do not make a mistake, if it is not normal tripping, excluding the quality of the circuit breaker itself, you have to check whether the circuit breaker selection is correct (the rated residual action current is respectively, check whether the electrical equipment and lines are normal, whether there is leakage or jumper possibility.

The leakage switch is assembled by an ordinary circuit breaker and a leakage module, with leakage protection function and short circuit protection, A1, A2 is the AC220V power supply inlet, A1 needs to be connected to the live wire, that is, the L phase; A2 needs to be connected to the zero line, that is, the n phase;

The two holes on the left side of the lower end are the wiring points that are assembled with the leakage module, we don't need to move it, the B1 and B2 on the right are the outlets, the same left is the live wire, and the right is the zero line outlet.

Please note: Don't make a mistake about the phase sequence of the incoming line, otherwise it won't play a protective role...

Delixi leakage switch DZ47LE should be wired like this:

1。The power supply is connected to the input side, and the load is connected to the output side. Both sides should be wired in accordance with the method of L connection to the live wire and N connection to the zero line, and each terminal must be firmly contacted.

2. After the connected zero wire passes through the leakage switch, it shall not be repeatedly grounded or connected to the exposed conductive part of the equipment.

3. Close the switch after connecting the wire, press the test button 3 times, and it should act correctly (that is, trip) before it can be put into trial operation.

4. The load test is divided into 3 times, and there can be no malfunction before it can be officially put into use.

5. The leakage switch installed separately should be easy to operate and maintain, and generally not more than meters from the ground.

The general leakage circuit breaker is wired using the principle of upper and lower line and outlet, you only need to distinguish the phase line and the zero line, between, the zero line is marked with n, and the inlet and outlet lines are the same.

dz stands for Plastic Case Circuit Breaker.

47 Manufacturer's design code.

LE Electronic Leakage Circuit Breaker.

63 Current Rating 63 Amps.

LE means with leakage protection, product model.

DZ47 is a universal model of domestic small air circuit breaker (also called micro breaker), which belongs to the same category of products as Schneider's C65 and ABB's S200;

LE is the meaning of leakage, and the general suffix le is to indicate that there is a leakage protection function, 63 indicates the frame current, that is, the maximum working current of this micro-break is 63A;

1N is this kind of micro-break belongs to the 1P+N type, and there are two pile heads in and out of the line, but there is no protective element at the N pole, which needs to be distinguished from the 2P micro-break. It is generally used at home, which not only satisfies the simultaneous disconnection of the line in the event of an accident, but also saves investment.

DZ47-63C32LE2P leakage circuit breaker, wiring live wire neutral line is not divided into left and right. Because the 2P leakage protector is broken at the same time, the zero line is broken.

Wiring Note: For 1P+N leakage circuit breakers.

There is no overload protection feature at the n pole, that is, there is no current tripping function.

If the power side is reversed, when the switch is turned off, the live wire is still live, because 1P+N only breaks the ** line, and the zero line is constantly opened.

If the input and output of the leakage protector are reversed, the trip coil of the electronic leakage protector will not be able to cut off the power when the power supply is cut off, resulting in a long-term power-on and burning.

2p, not strict, left zero right fire can.
