Since the circuit breaker is a safe electrical device, with the improvement of people's awareness of safety, circuit breakers can be seen everywhere in our country's homes. The circuit breaker was born earlier in 1885. Because the production equipment and technical means were not very perfect and pre-built at that time, the circuit breaker produced was not as good as what we see now. Now the circuit breaker produced by circuit breaker manufacturers has many advantages of its own, and its role plays an important role in life. Until now, the circuit breaker produced by Jiangxi Kerui Electric Co., Ltd. has added many features, which is convenient for everyone to use in daily life. So what are the main features of a powerful circuit breaker? Let's explain it to you one by one.
The rated ultimate short-circuit breaking capacity Icu, and the parameters in it not only consider its breaking capacity, but after it breaks several faults, it can still allow the device to work normally and play a good maintenance role. If it is a plastic case, Icu is enough to break the short-circuit switch and trip, as long as it is greater than 25% Icu, it is reasonable. In the current market, most of Ics are between (50%-75%) Icu.
One of the characteristics of the circuit breaker is the current limiting breaking capacity, as the name suggests, the ability to limit the fault current. When a short circuit occurs, this current-limiting breaking capacity will cause the contacts to open quickly, resulting in an arc, which hinders the increase of the fault current. The less time it is disconnected, the better it is implemented, and at the same time, it can reduce the electromagnetic effects and other dangers caused by short circuits. Electrodynamic and thermal effects do not have a bad effect on equipment, on the contrary it can lead to extended circuit breaker life.
The voltage and current involved in short-circuit protection are relatively dangerous, so related equipment has short-circuit protection. Short circuit protection can not only protect the safety of electricity, but also protect our personal safety. When I am using electricity, the circuit breaker is always working, always pay attention to the change of the current and electricity. When the electricity changes in the load, it is necessary to adjust the parameters set in the original year, so as to prevent frequent tripping from affecting the quality of electricity. It is also convenient to get up and has no worries. If the value you set is too large, there will be no good effect, and the device will not be protected from the original.
