Description

SA3W is a tape wound toroidal current transformer supplied without a moulded housing, which keeps the outside dimensions to a minimum. It suits retrofits and OEM assemblies where the transformer has to fit an envelope that already exists.

The core is wound and taped, then finished with insulated flying leads so it can be terminated wherever the assembly requires. Core size, turns ratio and lead length are all set at manufacture.

Features

  • Minimal outside dimensions for a given aperture
  • Insulated flying leads, length to order
  • Core size matched to the available space
  • Suitable for 1A or 5A secondaries

Applications

  • Retrofit metering in existing panels
  • OEM instrument and drive assemblies
  • Busbar current sensing
