PROTECTION LEVEL

It is a classification that indicates the level of protection provided by electrical equipment against the intrusion of foreign solid bodies (such as dust and objects) and the ingress of water.

IP23

They are suitable for use in indoor and sheltered environments. They offer protection against water droplets up to a maximum angle of 15°, and against solid objects with a diameter greater than 12.05 mm.
Button

IP54

They can be used in outdoor environments where they may be subject to adverse weather conditions, such as rain and dust.
Button

IP65

They can be used outdoors. They are fully protected against the entry of solid objects such as dust and water jets.
