We offer a super compact type of FC cutout with built-in ZnO elements, known as the ZnO element-equipped 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 greater discharge capacity compared to SiC elements, enabling 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 of a material that is particularly resistant to high temperatures and dryness. - The wire insertion openings 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 wide is not required (FC-30C, 50C). *For more details, please download the PDF or feel free to contact us.

We handle outdoor (general and salt-resistant) FC cutouts (box type) that are widely adopted by various power companies, railway companies, and facilities as primary protection switches for distribution transformers. In salt-damaged areas, they are used in combination with salt-resistant insulators. 【Features】 - When the fuse blows, the indicator part of the fuse tube pops out of the device to indicate 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. - 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.
