3-phase squirrel cage motors with flame-proof enclosure for belt-drives - 3SGf

3SGf motors are designed for operation in the mines endangered by the explosion of methane and

coal dust for driving of mining devices (e.g. impactors, conveyors). They comply with requirements of the

EN 60034-1, EN 60079-0 i EN 60079-1 standards for group I and PN-G-38010:1997 standard (for 1000V).

These motors belong to the category M2, 2G according to the Directive 94/9/WE (ATEX).
