OREANDA-NEWS. Mitsubishi Electric Corporation announced that it produced its milestone 30,000th gas circuit breaker (GCB) in the 72kV and higher class in Japan. GCBs protect electric facilities by cutting off irregular current in the case of accidents, such as lightning strikes to power grids.

Mitsubishi Electric's global shipments of GCB units now exceed 47,000 units, including those that have been manufactured by its U.S. affiliate Mitsubishi Electric Power Products, Inc. since 1986. Going forward, Mitsubishi Electric intends to contribute to electricity infrastructure worldwide through further improvements in product performance, reliability and maintenance.

Mitsubishi Electric has produced switchgear for the last half-century. Since its first 84/72kV GCB in 1965, the company has steadily enhanced performance to meet growing high-voltage and large-current power infrastructure needs around the world.
