LV HRC strip-type fuse-switch-disconnector are designed to receive NH fuse-links,Hinged fuse-carriers enable opening and closing operation in electric circuit under load conditions.Thereby,the fuse-link or solid link forms the moving contact.Both,single-pole and three pole switching is possible.It's mainly used in transformer stations and cable distribution s of pubic utilities as well as in low voltage switchgear and control gear assemblies .
to IEC/EN60439-1.Their closed design and high breaking capacity make them extremely reliable and powerful bination units.
