Carlo Gavazzi Controls S.p.A. CTA CTA DS ENG 08/02/2021 Split core current transformer
Description
Split core current transformer with compact dimensions, suitable for retrofit applications when used in combination with any energy meter with 5 A currents inputs. It manages primary current from 100 A to 600 A (depends on the model). Benefits
- Adaptability and flexibility. Effective for a wide range of currents, it can be installed in existent applications.
- Fast installation. The opening/closing mechanism makes installation fast even in existent applications. The analyzer only requires two cables to be connected per sensor.
Applications
CTA is the ideal solution for quick and easy installation without disconnecting cables during installation. It is indicated for any application (residential, commercial and industrial), especially for retrofitting where installing a solid core current transformer is not possible. Main features
- 5 A secondary current
- 24 mm hole diameter for primary current up to 300 A
- 36 mm hole diameter for primary current up to 600 A
