basic information
1. UL 1449 Listing certification obtained / NFPA79 compliant 2. Built-in disconnection device / SPD function display - The built-in disconnection device prevents smoke and fire from the SPD when the ZnO element deteriorates. - The disconnection mechanism includes an SPD function display. UL certified, NFPA79 compliant SPD (surge absorber) allows visual confirmation of function through the function display window. 3. Compact and space-saving - Integrated line-to-line and line-to-ground surge protection in one unit. - Miniaturization achieved by adopting multi-terminal elements, with the same dimensions for 200V to 500V models. 4. Reliable lightning surge resistance - Maximum discharge current of 5kA (8/20μs), resistant to large lightning surges. - Long lifespan, able to withstand 1000A lightning surges for 500 times. 5. Compliance with safety standards - EN 61643-11 TÜV certification obtained (TÜV SÜD Japan) - IEC 61643-11 - UL standards (UL 1449 Listing certification obtained) / CSA standards (C22. 2 No. 269) certification obtained, using flame-retardant materials (UL V-0). 6. Compliance with RoHS restricted substances - UL certification obtained for flame retardancy and insulation properties.

Company information
OTOWA is the only manufacturer in Japan specializing in lightning protection, having explored "lightning" since its founding. We want to create a safe and secure society where people are not afraid of the natural threat of "lightning." We will realize this wish with our advanced lightning protection systems. ◆ A wide range of product lineup We offer a variety of products, including surge protectors for power distribution, as well as those for offices, factories, railway vehicles, and general households. We also accommodate custom orders, so please feel free to consult with us. ◆ Consulting for lightning protection Lightning protection varies depending on various conditions such as location. OTOWA will propose the most suitable lightning protection measures for those conditions. ◆ World-class "lightning" testing facilities Using top-class testing equipment and a variety of testing facilities, we conduct product evaluation tests and development in-house. Our achievements are highly regarded, and we also accept contract testing (Lightning Technology Center). ◆ Unique quality of zinc oxide devices We produce zinc oxide (ZnO) devices under strict management. These devices are the heart of surge protective devices (SPDs) and are essential for lightning protection.
