![]() Stage Compartment - When located in a stage compartment, the air-disconnect switch isolates a single stage of a multi-stage capacitor bank, allowing for partial bank operation during maintenance. Incoming Compartment - When located in the incoming compartment, the air-disconnect switch provides a “visible break” or isolation for the entire power capacitor bank, allowing for safe access to all stages. IEC/ANSI indoor switches, switch-fuse combinations, disconnectors and load break switches up to 38.Depending on their location, the switches provide different functions, as follows:.The current transformers of the combined version form the mounting base for the earthing switch contacts thus reducing the space required in the cubicle. Recent addition to the range is the new GSec, designed to meet the specific requirements of the latest IEC standards.Įarthing switches come in two forms: independent earthing switches and combined earthing switches with integral current transformers. Gas-insulated switch disconnectors are based on sealed for life SF6 technology that offers high performance, reliability and long-life in a compact installation footprint. ![]() ANSI version is used in metal-enclosed switchgear, pad mounted cabinets, mining and capacitor switching applications. Air-insulated switch disconnectors are suitable for cable sectionalizer, transformer and motor circuit switching, in secondary distribution substations for supplying lines, transformers and ring networks, can be combined with DIN standard fuses for transformer protection.
