This web site shows part numbers appropriate for the vast majority of UK system applications with 230/240V single phase and 230/400, 240/415V three phase star connected supplies. In many international markets different voltage ratings and supply configurations are used. The table below gives order reference information for parallel configured, panel mount surge protective devices for international applications. The Model Designator remains constant (e.g. XT40, PTX048 etc.). Use the system designator selected from the table below to replace the UK system designator (e.g. 1P201, 3Y201), as appropriate for the application. Any additional requirements indicated by a suffix to the order reference number (e.g. SD for S.M.A.R.T. Diagnostics) also remain constant.

Example:
Order Reference number PTE080 3Y201 SD is The Protector® range, 80kA per phase surge suppressor with Active Tracking Network (ATN®) for connection to a three phase star wired system at 220/380V to 277/480V, including S.M.A.R.T. Diagnostics.
