Our power circuit breakers cover a full range of voltages from 15 kV class to 550 kV and developments are underway at 800 kV. These breakers have interrupting ratings from 25 kA to 80 kA.

 

All of our breakers are thoroughly tested in state-of-the-art facilities, including the High Voltage Lab, High Power Lab, Environmental Test Lab, and Seismic Test Lab of the Mitsubishi Electric ITAMI works in Japan. Complete factory production tests are also performed on each breaker at the Mitsubishi Electric Power Products production facility at Warrendale, PA. A summation of all the testing that goes into the circuit breaker product provides both Mitsubishi Electric Power Products and the customer assurance that the equipment will perform reliably in the field.
