Technical Data Construction Characteristics The MTW medium voltage switchgear is a medium voltage switchgear with a metal enclosure, which undergo an alkaline degrease treatment, phosphatization and powder painting. Overpressure relief devices on top or side provide pressure relief in case of internal arc. The general bus consists of one or more rectangular bars in electrolytic copper with tin plated fittings and dimensioned in such a way to withstand the thermal and dynamic efforts. The low voltage compartment is located in the upper front part. This compartment houses the measurement...

Technical Data Interlocks JJ nterconnections between the circuit breaker/contactor compartment door and its compartment do not allow access to them in I the "ON" position. JJ Interconnections between circuit breaker/contactor and earthing switch do not allow switching them on simultaneously JJ he circuit breaker/contactor can only be moved to the “TEST/EXTRACTED” position in the “OFF” condition without having to T open the switchgear door JJ The circuit breaker/contactor cannot be operated between the “INSERTED” and “TEST/EXTRACTED” positions JJ For the units equipped with contactors, in...
