basic information
*Features* 1. Built-in SPD separator allows for the shortest internal wiring. The built-in SPD separator eliminates external wiring between the SPD and the separator, significantly reducing wiring labor. By keeping the wiring as short as possible, optimal lightning protection can be achieved. 2. Easy installation within the panel, significantly reducing wiring labor. ● Complies with JIS standard dimensions for wiring circuit breakers (for 5 poles). ● Copper bars for branch MCCBs can be used. 3. Integrated SPD unit and connection terminal unit. The connection terminal unit can remain attached while the SPD unit is easily detachable by releasing the switch lever. 4. Inspection function with a disconnector that allows inspection while the main circuit breaker is energized. Connection terminal unit: During SPD replacement or inspection, the circuit can be opened using the switch lever, allowing work to be done without voltage. 5. Safety features even during degradation. ● Built-in automatic disconnection device. ● SPD function indicator included. ● Degradation contact output support (only for LT-TS2312S, LT-TS2304S). 6. Excellent responsiveness with no continuous current. 7. Three installation patterns available. ● DIN rail. ● Installation with M4 screws (tightening torque: 2.0 to 2.5 N·m). ● Connecting mounting plate. 8. Protects between lines and to ground with a single unit. 9. Complies with RoHS regulations on hazardous substances.

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.
