Engineering and procurement guidance for EK6 earthing switch and SW71 solid-insulated RMU core selection, interfaces and quotation inputs.
An earthing switch provides the grounding function within a switchgear arrangement. A solid-insulated RMU core integrates the primary switching and insulation path for a selected circuit-breaker, load-switch or switch-fuse unit. The required interfaces and operating duties are therefore different.
Provide the panel type, system voltage and short-circuit duty, mounting face, phase spacing, terminal direction, operating position, handle or mechanism interface, interlock requirement, drawing or photos, quantity and destination.
Identify the circuit-breaker, load-switch or switch-fuse unit, rated current, insulation and short-circuit duties, primary interface, phase layout, operating sequence, enclosure clearance, cable direction and required documents.
Send the selected EK6 or SW71 path, switchgear application, electrical duties, mechanical and interlock interfaces, current drawing or nameplate photos, quantity, destination, packing, inspection-document requirements and delivery schedule.
Send the selected EK6 or SW71 configuration with the switchgear application, electrical duties, unit type, mechanical interface, drawings, documents and delivery requirements for quotation.
