Anonymous Poster	Ingress Protection (IP) Classes 10/21/2009 7:53 AM
	Can I able to convert protection class of a component from IP40 to IP52. For example on panel say some 415V AC Distribution board which is IP52 protected, am using an MCCB with Direct rotary handle which is actually IP40 protected also flush mounted(door operated) on that panel. Is it necessary that the MCCB with Rotary handle should also meet IP52 what actually panel is? If so, is it possible to change the protection class of MCCB of IP40 to IP52? What I can do to make the MCCB as IP52 protected?In what manner I can acheive the IP52 protection from a IP40 protected device. please provide the solution.

	This is a common problem. Check with the manufacturer as they may have either an optional handle with a higher IP rating, or a seal or gasket that can be added to your existing handle to increase its IP rating. Alternatively (depending on the construction) you may be able to make a seal or seal the part with a sealant. This is a last resort however (for obvious reasons). __________________ jack of all trades

Hi, Please read the meaning of IP Class and act as per requirement of desired class. The chart below illustrates the use of special symbols in the IP classification system. In the "1st digit" columns, note the grid-like symbols next to numbers 5 and 6. In the "2nd digit" columns numbers 3–8 are symbolized by teardrop shaped symbols, sometimes enclosed in a box or a triangle, sometimes unenclosed (7–8). These symbols can be placed on equipment to illustrate the IP protection provided.


1st Digit	Protection from solid objects		2nd Digit	Protection from moisture

0	Non protected	0	Non protected

1	Protected against solid objects greater than 50mm	1	Protected against vertically dripping water

2	Protected against solid objects greater than 12.5mm	2	Protected against dripping water when tilted up to 15°

3	Protected against solid objects greater than 2.5mm	3	Protected against spraying water

4	Protected against solid objects greater than 1.0mm	4	Protected against splashing water

5	Dust protected	5	Protected against jetting water

6	Dust tight	6	Protected against powerfully jetting water

Note: IEC 60529 does not specify sealing effectiveness against the following: mechanical damage of the equipment; the risk of explosions; certain types of moisture conditions, e.g., those that are produced by condensation; corrosive vapors; fungus; vermin. Back to the top		7	Protected against the temporary effects of immersion

8	Protected against continuous submersion

	As told by Jack..., it is a very common problem. And, I don't think any manufacturer will supply an IP 52 Handle. You have to be content with IP 40. Or remove thedoor handle and provide a rotary operator on the MCCB toggle inside the panel itself and keep the panel IP 52.

	IP52 is uncommon: dust-protected and (only) dripping water protected together? IP54 or IP55 is more common. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	Dear Guest, Please introduce yourself. regarding you question on change of IP class, please remember that IP is related to mechanical which means ,you need to design the metal enclosure for that IP class only. So if you needed IP 54 or IP 55 , then during design stage itself, you should have provided a double door and a sliding canopy on the top( for water to slide down). The IP is applicable only when all the doors are closed and the panel is in operating condition. suppose if someone removes the doors ( for maintenance or by ignorance) the it is IP00. so to retain the IP class, the maintenance personnel must blow all the dust from the panel before putting the panel in operating condition. I thank our expert forum members who have given some excellent answers and practically explained about this aspect.
