FAQ

What is the purpose of an RLK-10 disconnect switch?

The RLK-10 is used to isolate de-energized sections of medium-voltage power systems and provide a visible break for maintenance safety.

Can the RLK-10 interrupt load current?

Standard RLK-10 disconnectors are designed for no-load switching. Special arc-extinguishing versions can interrupt limited load currents.

Is a grounding switch available?

Yes. Versions with one-side or two-side earthing switches are available.

Can polymer insulators replace porcelain?

Yes. Polymer insulators provide lighter weight, better pollution resistance, and reduced maintenance requirements
