The LA9GQQ330 is a Schneider TeSys connection bar — a pre-assembled set of conductors for wiring a 3-pole star-delta motor starter. It replaces the bundle of individual cables between the contactors and the motor terminals, keeping the panel build clean and repeatable. Rated for the TeSys frame, this bar carries the full motor current in star-delta transition. The set ships as a single unit — one connection bar per starter.
Fit and footprint
Physical size: 9.4 in deep, 13.8 in wide, 2.0 in high. That depth is the dimension from the mounting surface to the farthest conductor — critical for enclosure clearance. The 2.0 in height (50 mm) means it sits low on the DIN rail, leaving room above for control wiring. Operates up to 3000 m altitude without derating, 5000 m with a derating factor. For panels above 3000 m, account for reduced dielectric strength and cooling.
Designed to EN/IEC 60947-4-1, the standard for contactors and motor-starters. The connection bar is part of a system that must meet the same standard as the contactor itself. Lifecycle is active — no phase-out notice.
