What is IP Rating? (Ingress Protection Rating)


Electrical devices are found all across the world, in
very different working environments,and even in the home. A device that is suitable for a clean
environment like a medical process would be ineffective in a dirtier
environment such as steel foundry. In this video,we are going to discuss
the international rating system that classifies devices for
different environmental conditions. That rating system is called the Ingress Protection
or IP rating as it is commonly referred to. All electrical devices have an IP rating,
even the one you are watching this video on. before we get started on today’s video if you love our videos, be sure

international standard EN60529 and are used to set the levels of sealing
effectiveness of electrical enclosures and devices against intrusion from foreign
bodies such as dirt and water. The IP rating consists of two digits, such as IP68. Each having different protection and level. Having an international rating system such as the IP
rating allows for conformity of electrical devices guaranteeing that a device will be protected
the same in different parts of the world. Let’s break down the rating to better
understand what a rating means. The first digit in the IP rating is
the protection rating against solids. The first digit can be a zero up to a 6 and the
protection against solids increases from low to high. A rating of 0 states that the device or panel
has no special protection against solids. Protection level 1 protects from a
large part of the body such as a hand; from solid objects greater
than 50mm in diameter. Level 2 protects against fingers or other objects not
greater than 80mm in length and 12mm in diameter. Rating of 3 protects from entry by
tools, wires,and similar devices with a diameter of 2.5mm or more. A rating of 4 protects against
solid bodies larger than 1mm. Level 5 protects against dust
that may harm equipment. Ratings of 6 mean that the device
or panel is completely dust tight. The second digit in the IP rating is
the protection rating against liquids. The second digit can be a 0 up to an 8. Just like the first digit, the level of
protection increases from low to high. Protection level 0 states that the device or
panel has no special protection against liquids. A rating of 1, protects against
condensation and dripping water. Level 2 protects against water droplets
deflected up to 15o from vertical. A rating of 3 protects your device or
panel from spray up to 60o from vertical. A rating of 4 protects against
water spray from all directions. Level 5 protects against low-pressure
water jets from all directions. A rating of 6 means that the device or panel is
protected against strong water jets and waves. A rating of 7 protects against temporary
immersion of your device or panel. And finally, a rating of 8 protects against
prolonged effects of immersion under pressure. Now let’s talk about how two digits in the
IP rating go together as a full rating. All electrical devices that have an IP rating will
have a two-digit rating as we mentioned before. For example, if a device has a rating
of IP68 the device will be dust-tight and protected against long periods of
immersion in water under pressure. This example is both dust-tight and watertight according to the standards set up in the IP rating. Let’s look at another example; how about IP34. This device would be protected against
larger solid objects, something over 2.5mm, and protected against water
sprayed from all direction. With this rating, the device would most
likely need to be in some sort of enclosure because the solids protection
is only against large objects. Let’s look at a final example; IP61. Here there is full dust protection but the only liquid protection is for
vertically falling drops of water. This device could be outside of an enclosure assuming water is not going to be
used anywhere near the device. In closing, the IP rating or
ingress protection rating is an international standard set up for conformity in
solid and liquid protection for electrical devices. The IP rating is found on handheld devices and goes
all the way up to industrial electrical enclosures. The important things to
remember with the IP rating is that the first number covers
protection against solids, the second number covers liquid protection, and
the larger the digit the greater the protection. Want to learn PLC programming

  1. Next series Hazardous Location. Ex equipments. By the way, why are some devices marked ip66/67 instead of ip67 only?

  2. Thanks….. I am very excited of that subject's that realpars choosing to talk abouts…. effective subjects… And please don't forget about motion control lessons in both realpars YouTube channel and private site of realpars. Keep going

  3. In this day's I hear about (robot process automation) I searched in internet but I not achieve any specifications on RPA
    Because of that I now realpars is best in field of specification I extermly please realpars to make a introduction video about RPA with all my respect

  4. The IP rating has an equivalent NEMA rating. For instance, IP 14 is equivalent to NEMA 3R, IP 66 to NEMA 4X, and IP 67 to NEMA 6P. This is particularly important in electrical & instrumentation engineering design when selecting enclosures to protect equipment sensitives to dust and water.

  5. We will keep thank you forever , u have different and hard equation too .
    Simple + hard effort + enjoy learning + so clear + easy explain 🙂

  6. Hello saudações Amor graças 💖🙏🌷 pelas lindas palavras <3 parabéns pelo canal 🥰 obrigada por compartilhar ótimos vídeos 🙌🇧🇷👍
    Uma belíssima abençoada quinta-feira beijos com carinho 😘 Love

  7. This reminds me of the Underwriter's Laboratory (UL) rating/certification of "old'. Does this in any way tye-in? Supersede/replace? Is UL even in business anymore? I'd be curious how this compapres. What are your thoghts?

  8. This was a good video. Going off of this, could you consider doing a video on NEMA Enclosure types? Those have always been pretty tough for me. Thanks.

  9. I love this kind of video. You I realize you are good in a clear and easy explanation. Thank you very much!

  10. Just for accuracy, the IP stands for International Protection. It's published by the International Electrotechnical Commission as IEC 60529.

  11. i dont know why you stopped at ip68…where the ip69k is one of the best ip ratings..for food indsutry and other environments

  12. Never heard of this before because we use NEMA ratings, North America. IP just reminds me of Internet Protocol LOL, e.g. IPv4 or IPv6

  13. It should be noted that the water protection rating is not cumulative. While an IPX8 device will withstand freshwater submersion it may not survive high pressure jets.
