Degrees of protection

IP Code (International Protection Rating) as defined in IEC 60529.

This classifies the degree of protection provided by an enclosure against the ingress of solid objects and of water. The code consists of two digits, the first digit relating to solid objects, including body parts and the second relating to water. An additional letter indicates the degree of user protection afforded against direct contact with hazardous parts.

First digit of code Description Second digit of code Description
IP0X No protection. IPX0 No protection.
IP1X Protection against the penetration of objects of diameter Ø=50 mm, e.g. human palm. IPX1 Protection against water drops falling vertically.
IP2X Protection against the penetration of objects of diameter Ø=12 mm
e.g. palm finger.
 
IPX2 Protection against water drops falling at an angle = 150 from the vertical.
IP3X Protection against the penetration of objects of diameter Ø=2.5 mm. IPX3 Protection against water drops falling at an angle = 600 from the vertical (e.g.: rain)
IP4X Protection against the penetration of objects of diameter Ø=1.0 mm. IPX4 Protection against water splashing from any direction.
IP5X Protection against the penetration of any objects and settling of dust. IPX5 Protection against powerful water jets from any direction.
IP6X Dustproof. IPX6 Protection against water waves and powerful jets from any direction.
- - IPX7 Protection against destruction due to short-time (up to 30 min.) immersion in water, to the depth H=1 m.
- - IPX8 Protection against destruction due to long-time immersion in water, to the depth H>1 m.

Where the level of protection against electric shock is better than that indicated by the first digit of the IP code, an additional letter may be included. The letter code indicates protection against contact with dangerous voltage as follows:

Additional letter Description
A Protection against a direct contact with open palm of diameter Ø < 50 mm
B Protection against contact with finger of diameter Ø <12 mm and length < 80 mm
C Protection against contact with a tool of diameter Ø <2.5 mm and length < 100 mm
D Protection against contact with wire of diameter Ø <1,0 mm and length < 100 mm

Examples of IP protection degree for equipment manufactured by ELHAND are given below:
IP00 - no special protection of equipment
IP23 - protection against the penetration of objects of diameter Ø=12 mm, e.g. palm finger and against  water drops  falling at an angle = 600 from the vertical (e.g. rain)
IP44 - protection against the penetration of objects of diameter Ø=1.0 mm and water splashing from all directions
IP54 - protection against the penetration of any objects and dust settling and against water splashing from all directions
