Three-Phase Track Busway ROWs

Three-Phase Track Busway ROWs provide overhead power distribution for 208V and 480V applications in industrial environments. These ROWs support higher-capacity loads while maintaining plug-in flexibility for changing equipment layouts.

Three-Phase Power Distribution

These units tap two hot conductors to deliver line-to-line power:
-240V from a single-phase panel
-208V from a 120/208V three-phase panel
-480V from a 277/480V three-phase panel

BusBar Configurations

The busbar conductor layout determines the voltages available along the ROW.

Single-phase ROWs use three conductors (L-L-N) for 120V and 208Y systems.
Three-phase ROWs use four conductors (L-L-L-N) for 208/480V distribution.
