Enclosure/protection

(IP classes)

The right enclosure class is a prerequisite for an electric motor to work safely for a long period of time in tough loads and harsh environments. The enclosure class is specified according to SS-EN 60034-5: 2000 with the designation IP (International Protection) followed by two digits, for example IP 54.

BEVI's electric motors are normally in IP55 design, but can be delivered in most other designs on request.

See below for the meaning of the numbers.
