ABB M3GP ATEX Increased Safety Ex ec motors (Zone 2 gas)
The ABB M3GP Ex ec is the ATEX-certified "increased safety" version for Zone 2 gas environments, more cost-effective than Ex db when Zone 2 applies. IE3, 0.12 kW to 1000 kW.
What is an Ex ec motor?
An Ex ec motor (Increased safety, formerly Ex e) uses an optimised standard construction with additional safety measures to prevent internal sparking, no flameproof housing required. Applicable in Zone 2 (rare or no occurrence of explosive gas mixture). Significantly cheaper than Ex db and lighter, while amply safe for Zone 2.

Typical Zone 2 applications
Ex ec is the practical choice for industrial environments classified as Zone 2, often large parts of petrochemical installations.
- Petrochemical processing, outer tank fields, pipelines
- Bulk handling of flammable substances
- Warehouses for flammable liquids
- Outer parts of refineries
- General chemical plant locations with intermittent exposure
- Paint and coating industry outside direct spray zones
- Bio-fermentation tanks (alcohol substances)
When Ex ec versus Ex db?
Ex ec is only permitted in Zone 2. For Zone 1 or Zone 0 you need Ex db (M3JP/M3KP). When in doubt whether your zone classification is correct, we are happy to consult your ATEX zone document or perform an installation review.
