This case study focuses on the restoration and refurbishment of 30-year-old Secheron UR26 High-Speed Circuit Breakers for KiwiRail. IMTRAM is the authorised Australian and New Zealand service center for Secheron; a world-leading supplier of High-Speed AC and DC Circuit Breakers, Contactors, and Switches. This case study outlines the process followed by IMTRAM to breathe new life into the Secheron UR26 Circuit Breakers, prolonging their operational lifespan.

Yarra Trams, the operator of the tram network in Melbourne, Australia, operates a fleet of Combino trams which require regular maintenance and overhauls to ensure their continued safe and reliable operation. The brakes are a critical component of these trams and require specialized knowledge and expertise for their overhaul. This case study describes the successful completion of the 16-year overhaul of the Combino brake units by IMTRAM, the authorized service center for H&K and Secheron.

In 2020 Yarra Trams was required to upgrade some obsolete components of their Combino BCUs. Some parts were no longer available and IMTRAM provided a solution with partner Hanning & Kahl to upgrade some components in the BCUs as opposed to replacing them completely. This saved costs as well as materials as only some components were required to be replaced to make the BCUs future proof.
