The Panasonic Group is one of the world's largest electronics manufacturers, consisting of 496 companies, of which its environmental solutions company is responsible for the production of lighting, wiring and power distribution, housing equipment, switches, circuit breakers, etc., especially switches.
 
Panasonic's switches have been in the forefront since they entered China in 1987, and have successively launched about 20 series of more than 2,000 models. Even if Schneider, ABB and other famous European enterprises poured in, and domestic brands Delixi and Chint rose, Panasonic still has a good sales and reputation in the market with excellent performance and quality.
 
Compared with the "exposed" switch socket, the circuit breaker seems to be silent because it has been in the distribution box for many years, but in fact, the circuit breaker plays a vital role in protecting the entire family circuit, and Panasonic has never slackened in the production and quality control of the circuit breaker. In order to meet the rapidly growing demand for circuit breakers in Southeast Asia and parts of China, Panasonic expanded its circuit breaker factory in Vietnam in 2017, doubling its annual production capacity from 13 million pieces.
 
BD series is the main series of Panasonic household circuit breakers, which can also be subdivided into BD-63R and BDE-63R series, the former is an air switch, and the latter is a leakage protection switch. BD-63R air switch has 1P/2P/3P/4P four poles to choose from, the rated current level covers a total of 7 gears from 10A to 63A, to meet the needs of all families, 1P10A switch price of about 20 yuan, slightly lower than Siemens.
 
BD-63R electrical life is 6000 times, far exceeding the national standard 4000 times life standard, but compared with the 10000 times life of top manufacturers, there is still some gap, there is a status display window above the circuit breaker handle, through red, green, white respectively indicate open, closed, abnormal three states, users can quickly confirm whether the circuit is abnormal and take timely measures to protect the safety of electricity.
 
BDE-63R is a leakage protection switch, the letter "E" added in the middle stands for "electricity", when the leakage of electrical appliances in the home reaches 30mA, the switch will be disconnected to ensure the safety of users. The number of poles and rated current specifications of Panasonic leakage protection switch are not as much as that of air switches, only 2P and 4P two poles, and the rated current level covers 16A to 63A six gears, having said that, ordinary family use is more than enough, and generally choose a leakage protection switch with a current of more than 40A with a number of poles of 2P and a current of more than 40A as the main switch of the home circuit.
