1. 1、 Introction to circuit breaker (air switch)
circuit breaker, also known as air switch, also known as automatic switch, low voltage circuit breaker. The principle is: when the working current exceeds the rated current, short circuit, voltage loss and other circumstances, automatically cut off the circuit. At present, the common household switches are knife switch with porcelain plug-in fuse (which has been eliminated) or air switch (small circuit breaker with leakage protection). At present, DZ series air switches are commonly used in families with the following models / specifications: C16, C25, C32, C40, C60, C80, C100, C120 and other specifications. C represents tripping current, i.e. tripping current. For example, C32 represents 32 a tripping current. Generally, C32 is used for 6500w water heater installation, and C40 air switch is used for 7500w and 8500w water heater installation

3. Bar code management system, reliable bar code and anti-counterfeiting label double insurance system, double identification and double protection< Choose the ampere calculation method of circuit breaker (air switch)
1p = 735w ≈ 750W
1.5p = 1.5p × 750W = 1125w
2p = 2P × 750W = 1500W
2.5P = 2.5P × 750W = 1875W, and so on
(1) example: how many a air switches should be selected for 3 HP air conditioners 220 V)
750 W × 3PP = 2250w × 3 times (impulse current) = 6750w ÷ 220V=30.68A≈32A
(2) for example 5, how many a air switches should be selected 380V)
750W × 5pp = 3750w × 3 times (impulse current) = 1125w ÷ 380V = 29.60 ≈ 32A (power) ÷ Voltage = Ampere)
note: the average service life of air switch under rated load is 20000 times. In the understanding of the principle and function of leakage switch and air switch, in the process of selecting distribution box for customers, we should follow the principle of small lighting, medium socket and large air conditioner. According to the customer's requirements and decoration personality differences, combined with the actual situation of flexible distribution scheme. There are countless kinds of power distribution schemes. The following five common configuration scheme features and installation precautions are for customers' reference< 6. Miniature circuit breaker has the following protection functions, forms and technical characteristics; 2. Short circuit protection; 3. Overheat protection; 4. Phase to phase protection; 5. Under voltage protection; 6. Over voltage protection
VII. Polarity and expression method of circuit breaker (air switch)
single pole 220 V cut off live wire
double pole 220 V cut off live wire and zero wire at the same time

four-stage 380 V three-phase live wire one phase zero wire all cut off< 8. Purchase and installation
modern household electricity should be wired separately according to lighting circuit, power socket circuit, air conditioning circuit, etc. when one circuit (such as socket circuit) fails, other circuits can still supply power normally. Electric leakage protection device must be installed in the socket circuit to prevent electric leakage of household appliances from causing electric shock
1. Bipolar 32-63a miniature circuit breaker or isolating switch are generally selected as the main switch of household distribution box
2. Lighting circuit is usually 10-16a miniature circuit breaker
3. Generally 16-20A leakage protection circuit breaker is selected for socket circuit
4. 16-25a miniature circuit breaker is generally selected for air conditioning circuit
5. Bipolar or 1p + n (phase line + neutral line) circuit breaker is adopted to cut off the phase line and neutral line of the power supply immediately in case of short circuit or leakage fault, so as to ensure personal safety and safety of electrical equipment. The above selection is for reference only, the actual power of each household is different, the specific selection should be based on the electrician design.
