The LA9GTT330 is a star-delta connection bar set from Schneider Electric's TeSys range. It is used to wire three-phase motors in star-delta starting configurations, switching between start and run connections. The set complies with EN/IEC 60947-4-1 and is rated for altitudes up to 9842.52 ft (3000 m) without derating, and up to 5000 m with a derating factor applied.
Mounting & Dimensions
The bar set measures 25.5 in (648.5 mm) tall, 6.9 in (176 mm) wide, and 3.5 in (88 mm) deep. The 3P configuration uses three poles, typical for a standard star-delta circuit. The mechanical footprint is shared with the LA9GTS330 star-delta set, so panel cutouts for one will accept the other, assuming electrical ratings match.
