TUP50PR Measurement Transformers
El TUP50PR is a current transformer of double secondary for measurement and protection applications. Available in versions of measure, protection or combined, enables both functions to be integrated into a single unit with secondary configurations of x/1 A – x/5 A, x/1 A – x/1 A, or x/5 A – x/5 A.
Its construction, encapsulated in resin and its through-primary design for cable or busbar, provides a robust and reliable solution for industrial and electrical distribution installations.
