Manufactures of Isolated Phase Bus, and Telescopic Switches I.T.E. CIRCUIT BREAKER COMPANY OF USA, an ancestor company of SpecFab IPB, through successive corporate changes, has developed plants in Canada. These include: I.T.E. CANADA, I.T.E. IMPERIAL, R.I.E. CO., I.T.E. GOULD, BROWN BOVERI CANADA, and ABB CANADA. I.T.E. developed the IPB or (ISOLATED PHASE BUS) in 1937, to overcome high current and space limitation problems. SPECFAB IPB carries on a tradition of over 70 years of continuous service to the Power Generating Industry supplying Isolated Phase Bus equipment. A direct lineage of the transference of technical and manufacturing expertise, along with fabricating plant, can be traced to the development of the IPB concept of 1937 when the IPB was introduced by I.T.E.
