Feed-through current transformer (stranded wire/terminal)
Description
With feed-through current transformers, the primary conductor on the construction side is pushed through the current transformer opening in the housing. The feed-through opening is oriented towards the primary current strength. Wound current transformers have a primary winding and a secondary winding. Both windings are applied to the closed toroidal core and separated from each other by insulation. This principle is mainly used for small primary currents.
Advantages
- Stranded wires or terminals according to UL 94 V0
- Clip-on current transformer for direct conductor routing
- Design as wound transformer for small currents
- Ring band cores made of high-quality silicon iron
- Measurement in the lower frequency range 16 2/3 to 400Hz
- High core output power and high-quality insulation
- Electrically isolated primary and secondary circuits
- easy-to-install designs
- Versatile housing options with different through-hole openings
Advantages (mechanical)
- easy-to-install designs
- Variable connections e.g. terminals, plugs, flat plugs, stranded wires or PCB mounting
- versatile housing range with different
- Feed-through openings
- very long service life
