Standard trapeze hangerssupport Sentron Busway in horizontal applications on10 ft. (3.05m) centers. Additional hangers may beused if structural requirements mandate their use.The contractor must supply drop rods to completeassembly for trapeze hangers.Flat MountedEdge MountedSpring Hanger, Catalog NumbersCatalog Assembly floor to ceiling heightAmpere Rating 10ft. 12 ft. 14 ft. 16 ft. 18 ft.AL L-Rated225 — SXSH4 SXSH4 SXSH4 SXSH4 SXSH4400 — SXSH4 SXSH4 SXSH4 SXSH4 SXSH4600 — SXSH4 SXSH4 SXSH4 SXSH4 SXSH4800 400 SXSH4 SXSH4 SXSH4 SXSH4 SXSH41000 600 SXSH4 SXSH4 SXSH4 SXSH4 SXSH41200 800 SXSH4 SXSH4 SXSH4 SXSH4 SXSH41350 1000 SXSH4 SXSH4 SXSH4 SXSH4 SXSH41600 1200 SXSH4 SXSH4 SXSH4 SXSH4 SXSH42000 1350,1600 SXSH4 SXSH4 SXSH4 SXSH4 SXSH42500 2000 SXSH4 SXSH4 SXSH4 SXSH6 SXSH63000 2500 SXSH4 SXSH6 SXSH6 SXSH6 SXSH63200 2000 SXSH4 SXSH6 SXSH6 SXSH6 SXSH64000 3000,3200 SXSH4 SXSH6 SXSH6 SXSH6 SXSH8CU M-Rated225 — SXSH4 SXSH4 SXSH4 SXSH4 SXSH4400 — SXSH4 SXSH4 SXSH4 SXSH4 SXSH4600 — SXSH4 SXSH4 SXSH4 SXSH4 SXSH4800 400 SXSH4 SXSH4 SXSH4 SXSH4 SXSH41000 — SXSH4 SXSH4 SXSH4 SXSH4 SXSH41200 600 SXSH4 SXSH4 SXSH4 SXSH4 SXSH41350 800 SXSH4 SXSH4 SXSH4 SXSH6 SXSH61600 1000 SXSH4 SXSH4 SXSH6 SXSH6 SXSH62000 1200,1350 SXSH6 SXSH6 SXSH6 SXSH6 SXSH8— 1600 SXSH4 SXSH4 SXSH4 SXSH4 SXSH42500 2000 SXSH2 SXSH6 SXSH8 SXSH8 SXSH83000 — SXSH6 SXSH8 SXSH8 SXSH10 SXSH103200 — SXSH6 SXSH8 SXSH8 SXSH10 SXSH124000 2500,3000,3200 SXSH6 SXSH8 SXSH10 SXSH12 SXSH125000 4000 SXSH6 SXSH10 SXSH12 SXSH14 SXSH14Spring HangerSpring hangers and floor support hangers must beused to provide secure mounting of the busway runin vertical applications. Spring hangers support theweight of the busway on each floor and alsocompensate for minimal building movement andthermal expansion. Maximum distance betweenspring hangers may not exceed 16 ft. (4.88m). Whenordering 18 ft. (5.49m) floor to ceiling heightassemblies, intermediate support hangers arenecessary.**Note: Flanges do not offer support to the busway. Flanges provide ameans of covering the hole created in the existing structure.14-38Siemens Power Distribution & Control, SPEEDFAX 2007-2008 Product Catalog
