the Degree of protection indicates how well an electrical device is protected against the ingress of foreign bodies and water. It is given as an IP code , for example IP65. It is based on the standard DIN EN 60529.
How to read the IP code
- First digit (0–6): protection against solid foreign bodies and contact. From 2, no finger can reach dangerous parts; 5 means dust-protected, 6 dust-tight.
- Second digit (0–9): protection against water. 3 means protection against spray water such as rain, 5 against water jets, 6 against powerful water jets.
- X in one position means: the manufacturer makes no statement on this.
Which protection class where?
- Indoors, protected in the profile: a low protection class is enough, e.g. IP20 for the concealed VS-CKA 300
- Indoors, visible on the window: e.g. IP32 for the VS-KA chain drive
- Damp rooms, halls, outdoors or roof: IP65 or higher, e.g. VS-LA linear actuator and VS-ZA 800 (IP65) or VS-KA 2500 (IP66)
Protection class (IP) is not protection category
the Protection category (I, II, III), on the other hand, describes protection against electric shock. A 24 V actuator, for example, works with safety extra-low voltage. Both specifications are often side by side in the data sheet.
