IP Degree Selection
The IP degree must be chosen depending on the actual operating conditions of the places where switchgear and panel boards are installed.
When determining the right IP (Ingress Protection) level for your equipment, it is essential to consider the environment & conditions in which it will operate. The IEC standard 60529 defines the IP rating system, which determines the level of protection given by electrical equipment enclosures against foreign objects, dust, & water.
Understanding IP Ratings
An IP rating contains two digits:
First Digit: Protection against solid items and dust (0–6).
Second Digit: Represents the level of protection against water ingress (0-9).
Choosing the Right IP Degree: Evaluate the Environment
Indoor Use: If the equipment is utilized indoors in the controlled environment, a lower IP rating may be enough.
Outdoor Use: Outdoor equipment must have a higher IP rating to resist different weather conditions.
For Example
IP54 level of protection - according to IEC standard 60529 - is the answer when a distribution & motor control switchboard’s operational environment is dusty and damp, as in some industrial and tertiary sites.
Correct IP degree selection will greatly optimize switchgear dimensions and cost.
