Classification
Zone 1; Group IIBCENELEC Standard:
Group IIB; Category 2
Note:The classification in Zone 1 means that the motor is suitable to operate also in Zone 2 once Zone 1 represents an operating condition worse than Zone 2. The same applies to Groups and Categories: EEx d and EEx de motors are suitable to operate also in Group IIA and Category 3.
Certification
In Europe, WEG explosion proof motors meet ATEX Directive 94/9/EC certified by PTB and product certified by CESI -Centro Elettrotecnico Sperimentale Italiano S.P.A. The CESI certificates of conformity for explosion proof in flameproof enclosure d and de as per EN50014 / EN50018 are:EEx-d: Explosion proof motors (class of temperature T4)
EEx-de: Explosion proof motors with increased safety terminal box (class of temperature T4)
