Ang 40.5kV vacuum circuit breaker (VCB) na ito ay ginawa para sa gas-insulated switchgear (GIS) systems, nagbibigay ng tatlong posisyon na pagganap (breaking, isolating, and grounding) upang mapabilis ang high-voltage power control. Ito ay sumusuporta ng isang rated current na 1250A at breaking capacity na 31.5kA, nagbibigay ng maasahang proteksyon laban sa short circuits at overcurrents sa medium-to-high voltage grids.
Sa pamamagitan ng modular design, ito ay may kompak na struktura, mabuting performance sa pag-break, mataas na katiwalaan, mahabang serbisyo ng buhay, kompleto na isolation, walang pangangailangan ng maintenance, maliliit na footprint, at maaaring malawak na gamitin sa industriyal at sibil na ring networks at terminal power supply networks. Partikular na angkop para sa maliliit na secondary distribution stations, switch stations, industriyal at mining enterprises, airports, railways, highways, subways, commercial areas, residential areas, wind power, optoelectronics, at iba pang mga field.
