The AKH-0.66/MP series uses a flip-cover design with a transparent polycarbonate terminal cover for visible and convenient secondary wiring. Two windings are provided: one for measurement and one for protection. Its horizontal rectangular aperture can pass one to three busbars or multiple cables and is intended for electrical switchgear and low-voltage distribution protection systems.
