Compact switch-disconnectors are used tocontrol and isolate electrical distributioncircuits. In addition to these basicfunctions, other functions for safety, remotecontrol and convenience include:b earth-leakage protectionb auxiliary MN/MX releasesb remote operationb ammeter, etc.Compact switch-disconnectors may beinterlocked with another Compact switch-disconnector or circuit breaker to constitutea source-changeover system.
