Key Specifications
- Intended for switching of no-load circuits in MV switchgear panels, cabinets, and switching stations.
- Designed and manufactured in accordance with IEC 62271-102.
- Main frame and shafts are constructed from electro-galvanized steel for long-term corrosion resistance and structural integrity.
- Porcelain, epoxy resin or silicone rubber insulators with a specific creepage distance of not less than 12 mm/kV, in compliance with IEC 60815 pollution class requirements.
- Fixed and moving contacts are machined from electrolytic copper, silver- or nickel-plated, to maintain low and stable contact resistance throughout the service life.
- Suitable for installation and operation in both horizontal and vertical mounting orientations.
- Compatible with integrated fuse base and/or earthing switch.
- Custom configurations available on request.
