Mitsubishi Electric ships 10,000th gas circuit breaker

Warrendale, Pa., June 29, 2009 – Mitsubishi Electric Power Products, Inc. has shipped its 10,000th SF6 gas circuit breaker from the company’s newly expanded facility in Warrendale, Pa.

Initially, the breakers supplied to the U.S. 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.

The 10,000th breaker was destined for a substation serving renewable energy power generation in the Midwest.
