Vertiv Netsure 801DB

The NetSure 801DB distribution bay features high capacity, modularity, and simplified?installation. These features provide effective secondary load distribution and protection?for multiple -48 VDC feeds up to 640 amps (800 amps 20% derated). Each panel holds?up to 168 fuse or circuit breaker positions per bay. The 801DB may be configured for?2, 4, 6 or 8 busses.?The NetSure 801DB consists of a Zone 4 welded framework, with either six or eight?panels and top or bottom feed/distribution. The system offers a wide variety of options?including box frame extensions, internal ground bars with a paralleling feature that?permits multiple panels to be tied together, and transient voltage surge suppression.?The universal return bars can be mounted to overhead framing or a cable rack.?The bay is now available in 7′ H x 26″ W x 15″ D (2.13 m x 66.04 cm x 38.1 cm)?or a larger option: 7′ H x 30″ W x 24″ D (2.13 m x 76.2 cm x 60.96 cm).
