The Compact Plug-in Arrestors for Indoor
The compact plug-in indoor use arrestor series protects equipment by absorbing the induced lightning surge that appears in power or signal lines caused by lightning.
Features
- Small plug-in structure.
- The equipment is built so that the line does not open even if the body is pulled from the terminal, so it has excellent maintainability.
- The SR Series complies with JIS standards for power: C5381-1 (2004), and for the signal: C5381-21 (2004).
