IPIP 66 88
— IP suitability ratings are a system for classifying the degree of protection provided by enclosures of electrical equipment.
Protection against solid bodies Degree of protection for persons against access to hazardous parts inside the enclosure and/or against the ingress of solid foreign objects.
Protection against water Degree of protection of equipment inside enclosures against damage from the ingress of water.
No protection
No protection
Objects greater than 50 mm, accidental touch by hands
Protected against vertically falling drops of water
Objects greater than 12 mm, accidental touch by fingers
Protected against direct sprays of water 15° from vertical
Objects greater than 2.5 mm, e.g. tools/wires
Protected against sprays of water to 60° from vertical
Protected against water sprayed from all directions – limited ingress permitted Protected against low pressure jets of water from all directions – limited ingress permitted Protected against strong pressure jets of water, heavy seas – limited ingress permitted
Objects greater than 1 mm, e.g. tools/wires/small wires
Protected against dust – limited ingress (no harmful deposits)
Totally protected against dust (dust-tight)
Protection against the effects of immersion between 15 cm – 1 m
— 01
— 01 IP ratings
Protection against long periods of immersion under a quoted pressure, e.g. 2 bar at 24 hours IP69 Automotive standard DIN40050 and signifies resistance to high pressure jets of water (up to 80 bar) from any angle
The higher the number, the greater the degree of protection; they apply ONLY to properly installed equipment.
The second digit stands for protection against water
