The high-performance AR surge arrester absorbs the potential of an inductive lightning surge caused by a lightning discharge to protect electronic instruments. The plug-in arrester consists of a separable main unit and terminal block.
- Absorbs large surge voltages immediately.
- Simple circuit configuration and excellent adaptability to a distributed control system.
- Plug-in connection of the main unit with the terminal block, eliminating concerns about an open-circuit state even if the main unit is removed.
- Support JIS
