Isolated ground channel (optional) integrated channel design Datacenter A/B Exterior Color Coding standard is black ; red & blue option
Series DPB Bus Rail Coupler Technology • Improved Bus Rail Coupler is 50% less size, and doubled the number of contact points. Minimizes resistance and voltage drop. • Tested for 60degr C ambient (200-400A) • Compact design minimizes “Keep Out Area”, so more TapOff Boxes can be installed on the rails • No special tools required for installation • Supports BCMS communication cable for secure use of installation & maintenance 3.75” Industry Leading Keep Out Area
Series DPB Tap-Off Box Connection to Bus Rail Two Step Process insures Safety and Electrical Integrity STEP 1: Mechanical Connection All grounding connections engage & • seat directly to the open bus channel. Top Mast connects mechanically to • the bus rails. Set screws then insure alignment to rails. Rail design prevents backwards installation. STEP 2: Electrical Connection Once Top Mast is mechanically • secured, the cam action lever seats all electrical contacts against the phase bussing. Once energized, it locks down into position. At this point, the circuit breakers can be safely energized.
