WARRENDALE, PA--(Marketwire - June 29, 2009) - Mitsubishi Electric Power Products, Inc., the leader in high quality and highly reliable SF6 gas circuit breakers, has shipped its 10,000th unit from their newly expanded facility in Warrendale, Pa. A celebration was held in the factory on June 8 for all employees to mark the occasion.

Initially, the breakers supplied to the US market were built in Japan, by Mitsubishi Electric. In 1991, Mitsubishi Electric Power Products began subcontracting parts to local suppliers and assembling breakers in their original facility in Warrendale. Mitsubishi Electric Power Products shipped their first locally produced breaker to a domestic customer in 1991.

Mitsubishi Electric Power Products manufactures gas circuit breakers from 72kV to 550kV in Warrendale for sale to domestic and international customers. Expansion of the Warrendale facility was completed about a year ago to accommodate more office space and higher production capacity.

"Market demand is strong for our high-quality breakers, and with the recently completed expansion of our plant and process innovations from Japan, we expect it won't be long before we are celebrating our 20,000th breaker," said Ken Badaracco, general manager of the Gas Circuit Breaker Division.

The 10,000th breaker was destined for a substation serving renewable energy power generation in the Midwest, which is symbolic of Mitsubishi Electric's commitment to the environment. Environmental Vision 2021 is Mitsubishi Electric's long-term environmental management vision of the Mitsubishi Electric Group. This program establishes a framework for realizing a sustainable planet, defines long-term initiatives to protect the environment, and represents our commitment to society and to a clean environment.
