UL 2808 covers open-type current transformers used in energy monitoring applications.
It evaluates critical safety aspects including insulation, electrical spacings, dielectric withstand, thermal performance, materials, and mechanical integrity.
The split core structure allows the CT to be opened and installed around an existing conductor without disconnecting the primary circuit, saving time and installation cost.
√ UL 2808 Certified
√ Open-Type Split Core
