By separating the main and control circuits sections, we have enhanced safety when working in the control circuit section.
The vacuum valve makes full use of arc control technology and insulation design technology. Reliability has been improved through the pursuit of an optimal structure.

Allows inspection of the mechanical components by simply removing the face plate.
A centered design, in which the faceplate center and operating mechanism frame are aligned with the main circuit centre, has been adopted to further boost the design efficiency of the circuit boards.
It is also possible to inspect the mechanical components by simply removing the faceplate. In addition, we integrated accessible maintenance by installing lubrication holes in the operating mechanism.

Chromium-free steel sheets, which contain absolutely no hexavalent chromium (a soil contaminant), have been adopted, and in addition, a hexavalent chromium-free anti-corrosion treatment has been applied. Other harmful substances are also below the regulation values of the RoHS Directive, which came into effect in 2006, contributing to the construction of environmentally friendly data centres.

By downsizing the capacity of the operating power supply, the motor current can be reduced to about 1/4 of the conventional current. This was achieved by adopting a high-efficiency reduction gear and optimizing the motor characteristics to match the load torque.

With high quality and reliability, we respond to the needs of our customers and protect their data centre facilities, which are valuable assets to them.

A lineup of spring clamp terminals that do not use terminal screws is also available. These products contribute to shortening wiring time and the homogenization of installation quality by eliminating the need for screw tightening. Plus, it eliminates the need for retightening during inspections, which improves maintainability and contributes to cost reduction.

In compliance with the RoHS Directive, no harmful substances are used, and the product is designed in consideration of the environment.
By using recyclable materials and displaying the names of the materials used, we help reduce the environmental footprint of data centres through conscientious manufacturing.

Achieves the industry's smallest class dimensions with the high current limiting function of the new highly reliable breaking performance technology “arc running shut-off method.”* While maintaining the conventional breaking performance, the extremely compact size satisfies the need for miniaturization of circuit boards and mechanical devices.

In addition to JIS, IEC, GB, EN, UL/CSA standards, we support the export of circuit boards and devices globally by complying with the latest overseas standards such as KC of Korea and EAC of Russia. We provide safety and security to all parts of the world.

achieve "visualization" with energy-efficiency support devices and solutions that simplify the measurement, collection, and analysis of energy consumption. We support energy efficient activities by improving productivity and reducing costs.

“entire data centre optimization” can be achieved by accurately identifying the status of energy use, which varies from floor to floor and room to room, and analyzing and parsing how it is used. Mitsubishi Electric has a full lineup of products to achieve this.
Furthermore, by utilizing the visualized information, a highly flexible meter reading system can be established.
