How is the protection level of the distribution box divided?
How is the protection level of the distribution box divided? The IP (International Protection) protection rating system is drafted by the IEC (International ElectroTechnical Commission). The lamps are classified according to their characteristics of dust resistance, protection against foreign objects, water resistance, and moisture resistance. The foreign objects referred to here include tools, human fingers, and so on. Do not touch the live parts in the lamp to avoid electric shock. The IP protection level consists of two numbers. ** Numbers indicate the level of dust-proof and prevent foreign objects from entering the lamp; The second number indicates the degree of sealing of the lamp against moisture and water. The larger the number is, the higher the protection level is. ** The degree of protection indicated by the characteristic number (number) ** indicates the number: 0 No protection No special protection for people or things from the outside IP0-1 Prevent the intrusion of solid objects larger than 50mm and prevent the human body (such as the palm) Accidental contact with parts inside the lamp. Prevent large-size objects (diameter greater than 50mm) from intruding into IP1-2. Prevent solid objects larger than 12mm from invading, and prevent human fingers from touching the parts inside the lamp. Prevent medium size (diameter greater than 12mm, length greater than 80mm) foreign objects from intruding into IP2- 3 Prevent solid objects greater than 2.5mm from intruding, prevent tools, wires or similar small foreign objects from diameter or thickness intruding into contact The internal parts of the lamp IP3- 4 prevent the intrusion of solid objects greater than 1.0mm, prevent the intrusion of tools, wires or similar small foreign objects with a diameter or thickness greater than 1.0mm and contact the internal parts of the lamp IP4- 5 dust-proof, completely prevent Invasion of foreign objects. Although it cannot completely prevent the intrusion of dust, the amount of invaded dust does not affect the normal operation of the lamp. IP5- 6 The dust tightness completely prevents the intrusion of foreign objects, and it can completely prevent the intrusion of dust. IP6- The second marked characteristic number (number) The degree of protection refers to the second marked number: 0 No protection No special protection for outside people or objects IP-0 1 Prevent dripping water from entering, Vertical dripping water drops (such as condensate) will not cause harmful effects to the lamp IP-1 2 It can still prevent dripping water when it is tilted at 15 °. When the lamp is tilted from vertical to 15 °, dripping water will not cause harmful effects to the lamp. IP-2 Water sprayed in direction of 60 ° enters the lamp to cause damage to IP-3 4 Prevent splashing water from entering, prevent water from splashing into the lamp to cause damage to IP-4 5 Prevent sprayed water from entering, prevent nozzle from all directions The sprayed water enters the lamp and causes damage to IP-56. Prevents the intrusion of large waves. The lamp installed on the deck prevents the damage caused by water intrusion due to the intrusion of large waves. IP-6 7 Prevents the invasion of water when immersed in water. A certain period of time in the water or water pressure below a certain standard can ensure that no damage is caused by water ingress. IP-7 8 Prevents water intrusion during sinking, and the lamp sinks indefinitely as long as the water pressure is specified. Damage caused by water.
