Load Break Switch


BR10-PMS series SF6 insulated LBS

BR10-SPMS series solid dielectric LBS

The BR10-PMS/SPMS series padmount load break switches are installed on MV underground distribution lines and are used to branch or sectionalize lines.

They are divided into SF6 gas insulated and solid dielectric types depending on insulating medium, and motorized and manually operated types according to operation method.

The motorized load break switch has built-in voltage and current sensors as standard to monitor the status of distribution lines and detect line faults.

They guarantee constant operating speed and stable opening and closing operations regardless of the operator or method of operation by adopting the spring toggle mechanism.

BR10-PMS series SF6 gas insulated switches.

- BR10-PMS series switches consist of 4 or 3 three-phase load break switches with three-phase gang operated three-position rotary puffer switches including the position of earth switch in the same tank.

BR10-SPMS series solid dielectric switches.

- Switch and bus bar connection assemblies made of solid dielectric material with metal ground plane - Contact of earth switch insulated with environmentally friendly insulating fluids interlocking with the main contacts composed of vacuum interrupter
