Breakers related knowledge

Circuit breakers, also known as air switch , also known as automatic switch, low voltage circuit breakers . The principle is : when the operating current exceeds the rated current, short circuit, voltage , etc., automatically cut off the circuit . Currently, the total household switches are common knife switch with porcelain insert Insurance ( have been eliminated ) or air switch ( with a small leakage protection circuit breaker) . DZ series currently home use air switch , common with the following models / specifications : C10, C16, C25, C32, C40, C63 , and other specifications , where C is the trip current , namely off current, such as C32 , said off current of 32 amps .

An air conditioner breaker options

1 / 1.5 16A air -conditioned open

2 25A air -conditioned open

3 32A air -conditioned open

Note: air switch operation at rated load average life of 20,000 times.

2 circuit breakers ( air switch ) polarity and representation
Unipolar 1P 220V cut FireWire
FireWire and bipolar 2P 220V zero line while cutting
All three 3P 380V three-phase line cut
Four 4P 380V three-phase relative to the zero line firing line a whole cut .

3 . Optional installation
Modern home lighting circuits shall electricity , power outlet circuit , air conditioning circuit , separate wiring , when one loop ( eg outlet circuit ) fails, the other can still supply circuit normally. Outlet circuit leakage protection device must be installed to prevent leakage caused by personal electric appliances .
1 , total household distribution box switch generally choose bipolar 32-63A miniature circuit breaker or isolator switch.
2, the lighting circuit is generally 10-16A miniature circuit breaker .
3, the socket leakage protection circuit breaker generally choose the 16-20A .
4 , air-conditioning circuit generally choose 16-25A miniature circuit breaker .
5 , dual ? ? 1P + N ( FireWire + neutral) wire circuit breaker , when a short circuit or leakage fault line , immediately cut off the power supply line and neutral to ensure personal safety and the safety of electrical equipment . More choice for reference only, actual household appliances power is not the same , according to the specific choice of electrical design prevail.

4 security identification

1 Chint breaker , at the bottom of the product has a unique bar code , you can call 0577-62777777 check the authenticity .

2 on the side of the circuit breaker , there is a very clear sign stenciled Chint .
