Overview Busbar systems distribute power throughout a panel by enabling components to be mounted onto adapters that snap onto three copper bars attached to end supports connected to the back panel. Establishing an electrical connection and mechanically fastening in one step, this design reduces wiring time by up to 40 percent and allows power to be easily distributed to multiple components while being touch-safe rated to IP20. In addition, busbar systems utilize pre-wired adapters and sliding DIN rails, enabling components to be placed closer together while reducing the raceway and bending radius space required. With this arrangement, the 60-mm Busbar System consumes up to 25 percent less panel space than traditional wiring. Application • Distributes 3-phase power, up to 690V, coming from a main breaker or fuse block; can also be used for single-phase and DC applications • Convenient solution for delivering power throughout panels containing smaller devices and fed by a 100 A or higher main breaker • Provides direct mounting solutions for major component manufacturers (ABB, Allen-Bradley, Eaton Cutler-Hammer, General Electric, Merlin Gerlin, Moeller, Siemens ITE, Schneider Square D®) Features • The 60-mm on-center distance of the busbars minimizes the overall footprint, allowing large ampacities to be distributed in a small space • Ampacity range of 0-I767A covers most key applications • Reduces panel wiring time by up to 40 percent versus conventional wiring • Electrical and mechanical connections are completed in one step • The design and layout are efficient and can be changed at any time; innovative terminal solutions connect wires directly to the busbar system; no drilling or tapping is required • Requires up to 25 percent less panel space than conventional wiring by eliminating some raceway and reducing bending radius space • Provides the highest standard of safety; designed to be touch-safe to IP20 • Snap-together design makes planning, project design and installation easy; fuses, fuse bases and fuse switch disconnectors are simply "clicked" onto the busbars		• Application versatility reduces inventory requirements • Adapts to most cabinets and enclosures; position busbars vertically or horizontally anywhere within grid dimensions for optimum use of space • Add components easily to extend the panel; number of connections is minimized • Shielded connections reduce arc flash danger Construction • Busbar is constructed of tinned copper for superior corrosion resistance Industry Standards UL 508A Component Recognized, File No. EI23577, E230I63, EI97039 CSA Certified Technical Information Drawings can be found on hoffmanonline.com.
