ProLine Panelboards

ProLine panelboards are the perfect and compact solution for applications where reliable power distribution is critical to their operations. They provide an innovative and high-performance approach to branch circuit protection by featuring PLU700M based on SUP200M and S800U Miniature Circuit Breakers (MCBs). ProLine panelboards are the electrical industry’s first current-limiting, touch-safe and fully coordinated UL 67 panelboard.

Upgrades to ProLine panelboards
ProLine breakers and bus connectors can now be ordered separately without being assembled by ABB to increase flexibility and reduce lead times for our customers. The Tmax T main breaker has also been converted to Tmax XT to offer a higher series rating.
