Protective construction
Expresses the degree of protective construction that guards the level of functionability of the switch against ingress of solid
objects, water, and oil. The standards are IEC529 (IEC: International Electrotechnical Commission) standards. IEC standards
determine the level of protection against both water and solid objects, but not against oil.
Protection against both water and solid objects
PROTECTIVE CONSTRUCTION
0—
No particular protection
4—
Protection against solid
objects exceeding
1mm .039inch in size.
A hard wire 1mm dia. .039 inch dia. across cannot
penetrate the inside.
5—
Protection against dust
The unit is left for 8 hours in an atmosphere in which
2kg of talcum powder per 1m3 is floating. No damage
incurred from talcum powder penetrating the inside.
6
Dust-proof
Protection againt dust
(dust does not penetrate)
The unit is left for 8 hours in an atmosphere in which
2kg of talcum powder per 1m3 is floating. The talcum
powder does not penetrate the inside.
3
Rain-proof
Protection against rain fall
No damage incurred when sprayed with water
continuously for 10 minutes at angles of up to 60°
from the perpendicular.
4
Foam-proof
Protection against flying foam
No damage incurred when sprayed with water
continuously for 10 minutes at angles of up to 180°
from the perpendicular across a wide area.
5
Spray-proof
6
Water proof
Protection against waves
Water does not invade the interior when sprayed with
a jet of water for 3 minutes from all directions, as per
the diagram on the left.
7
Corrosion-
proof
Protection against corrosion while
immersed in water
Water does not invade the interior during immersion
for 30 minutes at a depth of 1m 3.281ft..
Protection
against water
Protection against
solid objects

□ □
Note: 1. All of the tests cited above were conducted with the cord vent (conduit vent) tightly shut.
2. The above protective constructions are based on IEC standard but major differences may arise due to length of use and operating environment.
This should be thoroughly discussed and verified.
3. When the corrosion-proof model is immersed in water for 30 minutes or more, verify that no water has penetrated the inside before use.
