An extensive range of high quality current transformers offering comprehensive measuring and protection class accuracies. The range provides accurate measurement of high primary currents and ratio matching to a consistent 5 or 1 Amp secondary current, proportional to the main current. To suit the requirements of every application, the range offers moulded case, miniature, core balanced, tape wound and split core current transformers and integral transducers in a wide range of system current ratings, busbar sizes, case widths and apertures, with various mounting options.

Providing both quality and experience the Setzermann division of REO INDUCTIVE COMPONENTS AG produces toroidal current-transformers from with power ratings from 10 VA up to 500 VA. These are available in either standard or custom designs, built to specification and proved in our own test laboratory. The toroidal current-transformers conform to all relevant standards whilst double-isolation and the use of UL approved encapsulation materials are always incorporated in their design. The Setzermann range of current-transformers includes many different styles from those for pcb-mounting to panel-mounting types. We offer our customers a prototyping service before commitment to a final design. Details of all products can be downloaded from our website. Setzermann current-transformers have a good reputation for high-protection and longevity.
