The air switch is so many models, various letters, so what does the letter stand for?
In general, D stands for power, C stands for tripping current, i.e., jump current.
1. The domestic air opening is basically DZ, with leakage protection, the following models/specifications are common: C16, C25, C32, C40, C60, C80, C100, C120 and other specifications.
Ii. General DW and DZ models are used in the above industries.
20,32,50,63,80,100,125,160,250,400,600,800,1000...
(unit A).

Explanation: for example, C32 indicates that the starting current is 32, the general installation of 6500W water heater is C32, and the installation of 7500W and 8500W water heater is to be opened with C40.
Another specific model: dz47-60a C25.
DZ47- series of miniature circuit breakers (and many series, which are basically named by the manufacturer)
LE---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ----
C--- instantaneous tripping over flow multiple according to the Ming class, such as 5~7 or 7~10 times, D is 10~14 times power type.
Let's talk about what type of space should be used in specific applications:
1. DZ5 series: applicable to the circuit of 50HZ, 380V and rated current from 0.15a to 50A.
2. DZ10 series: applicable to ac 50HZ, 380V or dc 220V and below.
3. DZ12 series: suitable for communication 50HZ single-phase 230V circuit, mainly installed in hotel, apartment, high-rise building, square, air port, railway station and other lighting distribution boxes.
4. DZ15 series: applicable to the circuit with ac 50HZ, rated voltage 380V, rated current 63A.
5. DZ20 series: applicable to ac 50HZ, rated insulation voltage 660V, rated voltage 380V and below, rated current to 1250A.
6. DZ47 series: applicable to ac 50HZ/60HZ, rated operating voltage of 240V/415V and below, rated current to 60A circuit.
7. DW15 series: suitable for ac 50HZ, rated voltage to 440V, rated working voltage to 1140V, 80V distribution network.
8. SCML series: suitable for ac 50HZ, 60HZ, 500V and below.
9. DW10 series: suitable for ac 50HZ, rated voltage to 440V electrical wiring.
10. AC30 series: it is applicable to the auxiliary electrical components of the modular terminal assembly, and can also be installed with other complete sets of electrical appliances for plugging in the electrical equipment.
11, H series: apply to the rated current under 600 a and, ac 50 hz, rated voltage 690 v and below, dc 230 v and below, generally by electrophoresis, fixed current under 225 a and air switch, respectively as the lines and not infrequently of frequency conversion and motor starting.
