Through-hole current transformer (module base)
Description
With through-hole current transformers, the primary conductor provided by the customer 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.
Advantages
- Bolt or flat plug connection
- Through-hole current transformer for direct conductor routing
- Toroidal cores made of high-quality magnetic cores
- Frequency range 16 2/3 to 400 Hz optional
- High core output power and high-quality insulation
- Electrically isolated primary and secondary circuits
- Easy-to-install module housings
- Variable connections, e.g., bolts, plugs, flat plugs, strands
- Versatile housing options with different through-hole openings
