The HySec multifunctional device includes the functions of three different devices: circuit breaker, disconnector and earthing switch. This unit is ideal for use in medium voltage switchgear for secondary power distribution.
The upper part of the apparatus acts as a switch and contains three vacuum interrupters in an epoxy resin housing.
The lower part made of stainless steel serves as a line disconnector (partition between the cable and bus compartments) and an earthing switch (for earthing the cables themselves).
