When the post-80s and post-90s have become the leading forces in the new consumer era, our imagination of modern home furnishings has undergone brand-new changes in depth and breadth. The ideal home is smarter, more efficient, and more convenient than in the past. Various new types of electrical appliances need to replace our hands to work and assist our brains to give instructions. Behind all these dream lives, the maintenance of electric energy is inseparable, which increases the risk of circuit overload, short circuit, and leakage. At this time, it is even more necessary for us to understand how the circuit breaker, the first protector of safe electricity use, can solve the problem concentratedly and quickly when the electricity risk comes.
Circuit breakers are mainly divided into two common types according to their functions: air switch and leakage protector. The former mainly protects "objects", that is, circuits or electrical appliances will not be burned due to overheating of wires; the latter mainly focuses on protection. "Person" means to cut off the circuit in time when the electricity leaks to prevent the risk of electric shock and protect the safety of family members.
Aiming at the reality that new electrical appliances in modern homes rely heavily on and consume electricity for a long time, Siemens has pioneered the "Home Electrical Strong and Weak Current Whole House Solution", which integrates the transmission, distribution and safe use of electrical energy in the home environment, and arranges it in a reasonable manner. Strong and weak electricity, multi-dimensional protection of household electricity safety. Here is an example of Siemens Green Break series leakage protectors to introduce important inspection criteria when purchasing:
1.Is the product shell resistant to high temperature
The circuit breaker chosen in order to prevent electrical fires at home must not become a hidden danger itself. If you choose a circuit breaker with a thermoplastic shell by mistake, there will be a risk of high temperature ignition and continuous burning. Even some products with flame retardants will continue to produce toxicity, which will affect your health for a long time. The Siemens green circuit breaker series specially selects a higher-quality thermosetting shell, does not use flame retardants, and in the case of high leakage and insulation damage, it can be extinguished by itself when sparks occur, and no ignition occurs. It does not melt and deform, and it is not easy to deform when working at high temperatures, which can provide multiple safety guarantees for the stability of the family.

2.Is the short circuit arc extinguishing speed fast enough?
The arc extinguishing system of household circuit breakers usually adopts grid extinguishing to divide the fault arc into many small arcs. The arc extinguishing speed can be increased by increasing the number of grids. It is fast enough to be able to timely when the electricity risk comes. Provide effective security protection.
Siemens specially selects high-quality short-circuit integrated arc extinguishing system, using 13 ultra-wide copper-plated grids. Compared with similar products with 9 common arc extinguishing grids on the market, the arc extinguishing response is faster. , Siemens Green Break series can achieve the shortest short-circuit arc extinguishing of 2.5 milliseconds, which is far better than the general standard requirement of 0.1 second.

Circuit breakers are the nerve center of home electrical safety management. With the efficient coordination of Siemens Home Electrical, strong currents are safer and weak currents are more efficient, effectively adding safety locks to a safe and comfortable living environment, and ensuring the safety of the whole house in all directions. Protect the health of your family.
