Busbar system Busbar center-to-center spacing 60 mm Device adapter, Width: 55 mm Bar thickness: 5.10 mm+TT profile for contactor with overload relay 3R, S2 with 1 DIN rail 35 mm, up to 56 A Length 182 mm 8US busbar system for setting up protective devices such as fuse switch disconnectors and circuit breakers – safe, space-saving and clearly laid out. The use of the 8US busbar systems from Siemens gives a number of options for installing rail-adaptable connecting, switching and installation devices. Cost-effective electrotechnical enhancement of modern distribution boards is possible due to their small footprint, compact design and quick assembly contacts. Mounting is on longitudinal stays and the rail gap is 60 mm. Key features of the Siemens 8US busbar systems: 1. Mechanical fixing and electrical contacting in a single step. 2. Worldwide approval and therefore worldwide use in mechanical and plant engineering. 3. Easy replacement of individual devices or entire combinations. 4. Time savings and cost reductions in installation with preassembled load feeders. 5. High operational safety with finger-safe adapter and device holder covers. 6. Large range of busbars can be used for easy adjustment to currents of up to 1,600 A. &DPMD_ACC602_001_000_1001458&
