LS Busway's Ex-way is a totally enclosed, non-ventilated, true-sandwich design rated at 600V and engineered for demanding power distribution needs. This advanced busway system supports current ratings from 630A to 6000A and is available with either copper or aluminum conductors. 

Designed for both performance and durability, Ex-way busway features an all-aluminum, two-piece housing that provides excellent mechanical strength and superior heat dissipation. This makes it a reliable busway solution for a wide range of commercial and industrial applications. 

The Ex-way busway system is capable of handling up to AC 1000V.  When paired with our high-performance joint kit, the large, connected surface reduces contact resistance and meets NEMA 3 weather-resistant standards. Depending on your project requirements, LS Busway's Ex-way is available with interior or exterior NEMA 3R-rated housing, or NEMA 1 for indoor installations.
