What it is and what it does
The ABB A9N00S-84E is a 3-phase non-metallic enclosure from the A9N series, Size 00, straight-through configuration. It houses and protects electrical distribution components — breakers, contactors, terminals — in a compact, non-corrosive enclosure suited for indoor or sheltered outdoor use. The non-metallic construction eliminates ground-loop paths and resists condensation better than painted steel in humid environments.
Integration note
Size 00 footprint — typically accepts a single 3-pole breaker or contactor up to 30 A class. Straight-through cable entry simplifies panel layout: line in at the top, load out the bottom. Non-metallic means no bonding jumper needed for the enclosure itself, but the internal grounding bus (if fitted) must be tied to the system ground. Mounts via external flanges or a backplate; verify the knock-out pattern matches your conduit or cable gland plan before committing.
