Protection class

The motor’s design version corresponds to the following protection classes:

  • Flameproof enclosure (ATEX)
  • Explosionproof (FM)
  • Flameproof enclosures (CSA-EX)

In order to limit the surface temperature, the motor must be equipped with at least one temperature limiter (1‑circuit temperature monitoring). It may also be equipped with a temperature controller (2‑circuit temperature monitoring).
