• Power distribution and control panels

The "NEAS Series" is a high-voltage air-insulated switchgear with overcurrent lock type that achieves industry-leading compactness and lightweight design. It aims to prevent the spread of accidents from high-voltage users and minimize damage within the user’s premises. It is particularly suitable for sectional switchgear at the responsibility boundary point in high-voltage user facilities, as well as for 3.3kV or 6.6kV high-voltage sectional switchgear within user premises. 【Features】 ■ Achieves industry-leading compactness and lightweight design ■ Standard use of stainless steel casing ■ Improved workability ■ Built-in lightning arrester / Built-in voltage transformer and lightning arrester for enhanced lightning protection and usability *For more details, please download the PDF or feel free to contact us.

• Power distribution and control panels

We offer a super compact type of FC cutout with built-in ZnO elements, known as the ZnO element FC cutout (box type). When a lightning surge enters, the ZnO element suppresses the voltage and eliminates the lightning surge. This helps prevent fuse blowouts and contributes to the prevention of equipment failures due to lightning damage. 【Features】 - More space-saving and economical than using lightning arresters and cutouts separately - No fuse blowouts due to lightning surges - Excellent non-linearity, effectively suppressing lightning surges without continuous current, and performs well under multiple lightning responsibilities - Smaller cross-sectional area with high discharge capacity compared to SiC elements, allowing for miniaturization - High performance and high reliability that exceed JIS standard values *For more details, please download the PDF or feel free to contact us.

We offer indoor (cubicle) FC cutouts designed to make effective use of space within cubicles. The wire insertion holes are available in both vertical and horizontal orientations. They are compact, lightweight, economical, and easy to assemble. 【Features】 - The fuse tube is made from materials that are particularly resistant to high temperatures and dryness. - The wire insertion points for connections are installed in a vertical orientation (FC-30C, 50C). - The installation spacing for the FC cutouts can be significantly reduced (FC-30C, 50C). - A stopper bracket (plate) to prevent the lid from opening too far is unnecessary (FC-30C, 50C). *For more details, please download the PDF or feel free to contact us.

• Power distribution and control panels

We handle outdoor (general use and salt-resistant) FC cutouts (box type) that are widely adopted by various power companies, railway companies, and business establishments as primary side protection switches for distribution transformers. In salt damage areas, they are used in combination with salt-resistant supporting insulators. 【Features】 - When the fuse blows, the indicator part of the fuse tube pops out of the device, signaling a blown fuse. - The indicator part is red, making it visible from the ground. - The operation rod allows for safe and easy opening and closing operations. - The fuse tube has excellent mechanical strength, easily interrupting the specified short-circuit current. - The body and lid are made of ceramic, ensuring no deterioration and maintaining high dielectric strength. *For more details, please download the PDF or feel free to contact us.
