Ring Main Unit
Compact medium-voltage distribution and protection options for utility, commercial and renewable-energy networks.
OVERVIEW
Configured for the actual electrical system.
Feeder arrangement, load-break switches, circuit breakers, fuses, metering, automation interfaces and insulation technology are selected around the network scheme and local rules.
Typical ranges on this page are for preliminary project selection only. Final design, materials, performance, tests, certificates and supply scope are subject to the signed project technical agreement and the selected manufacturing partner.
