Introduction:
With IEC60439-3 standard, LWHT series distribution box is attractive and durable, safe and reliable, which is widely used in various places such as factories, mansions, residences, shopping centers and so on.
In the communication power supply system, 4 way plastic distribution box the function that the power supply equipment is automatically disconnected due to excessive load is called overload protection.Overload can refer to too much load on an electrical device or to too much action on a body.The protection against these "overload" actions is collectively called overload protection.
In the field of communication power supply, the overload protection function is usually realized by air switch and fuse, and the overload protection function can be realized by placing an air switch or fuse in the power supply line.The amount of current in an electrical line that is allowed to pass continuously without overheating the line.When the load is too large, the current flowing through a wire exceeds its safe carrying capacity. This is called overload.The overload of the wire will lead to the increase of the temperature of the wire. The maximum allowable working temperature of the wire is 65℃.Conductor overload, conductor temperature exceeds the maximum allowable operating temperature, will lead to rapid aging of conductor insulation layer and even cause fire line combustion.Therefore, in the actual power supply line, 4 way plastic distribution box we often have the function of overload protection equipment to prevent the load from leading to safety risks.
