Through-hole current transformers (PIN version)
Description
With through-hole current transformers, the primary conductor on the construction side is inserted through the current transformer opening in the housing. The through-hole opening is oriented to the primary current strength. Wound current transformers have a primary winding and a secondary winding. Both windings are applied to the closed ring core and separated from each other by insulation. This principle is predominantly used for small primary currents.
