This bus bar carries an NRND (Not Recommended for New Designs) lifecycle status.
The bus bar integrates directly with the 3VU13 motor starter protector family, snapping onto the line side to feed three-phase power without individual wiring per device. Its 140 x 50 x 14 mm footprint and 1-piece packaging suit it for panel integration where space is tight and a common bus is preferred over daisy-chaining.
