Mersen Introduces USBB UltraSafe™ Bus Bar System

Newburyport, MA, -- Mersen (formerly Ferraz Shawmut) introduces its new USBB UltraSafe™ bus bar system. Intended for use with UltraSafe™ Class CC (USCC) and Midget (USM) fuseholders, the USBB delivers a safe and reliable combination of circuits in a compact design.

Mersen's USBB UltraSafe™ bus bar system reduces installation time when compared to traditional wire solutions. It also offers space savings and a touch-safe, shock-resistant solution for panel builders and designers. Covers for unused poles are also available. The USBB saves valuable panel space with its compact design and footprint. It is RoHS compliant and lead-free.

"The design features of this product were the result of research indicating the need for a bus bar system that was smaller and safer, with cost savings that could be passed on to end customers", says Bob Lyons, Mersen product manager.

The USBB UltraSafe™ is ideal for applications such as UL 508 panels, solar string combiner boxes, control panels, and power distribution panels.
