Process Control and Electric Motor instrument transformers

This CT range is in cast resin, with excellent withstand to severe environment in terms of temperature, vibrations, salt, moisture and contaminants.

Secondary terminal connections are flying leads, to avoid any potential risk of loosening connections, or vibration resonance that may break terminals. TR33xy and TR66xy are designed to adapt to various busbar sizes, and accommodate large cores and windings to match demanding requirements in protection and accuracy classes. Fixing is performed tightening 2 horse shoe-shape clips on amagnetic support plate, enabling very strong hold on busbar.
