Description
Explosion-protected electric motors are used in industrial plants with a potentially explosive atmosphere, containing inflamable fumes (vapours) or gases (i.e. chemical industry, oil refineries,...) as well as in mines where methane is present. The enclosures of electric motors are designed to be "flameproof" according to EN 60079-0 (IEC 60079-1). The terminal boxes could also be in "flameproof" design or also in "increased safety" design according to EN 60079-7 (IEC 60079-7).
Technical Data
These are three-phase asynchronous electric motors with shot-circuit rotor, according to the EN 60079-0, EN 600079-1, EN 600079-7 and EN 60079-31 standards.
