How to make good use of the “electric housekeeper” in the dormitory – optional power-limited protector

he most feared thing about electricity in the dormitory is the secret use of high-power electrical appliances that cause tripping or even fire. For everyone’s safety, many school dormitories, rental houses and shopping malls are now installed.”Selective power-limited protectors”。 What is this thing? How can I use it so as not to be upset? Let’s talk about it in the vernacular today. ! [JGXZ series.]Selective power-limited protectors

To put it simply, this protector is a strict “electric housekeeper”. It mainly has two brushes: one is to limit the power of a single appliance, for example, if you want to secretly use a high-power electric cooker, it will immediately recognize and cut off the power; The second is to limit the total power, even if everyone is using small appliances, it will “shoot” to protect the line. For example, the commonly used JGXZ series, it can be accurately controlled, the total power limit is set at 2.0kW, and the limit for a single appliance is 0.2kW.

Here’s a practical tip: don’t get stuck too hard when setting a single power limit! If the actual power of your appliance is 200W, it is best to leave some margin when setting it to about 220W (it is recommended to be 10%-15% larger than the actual power). In addition, do not connect two large electrical appliances of the same power at the same time, otherwise the protector will be mistakenly judged as an ultra-high-power device and directly pull the brake. In short, use this protector well not only for safety, but also to avoid embarrassment in life. As long as the settings are reasonable, electricity can be more worry-free and safer!
