20ka Surge Protection Device 4P AC Anti‑Thunder Modular Application:
• Widely used in workshops, outdoor monitoring boxes, companies, households, etc.
• BR-20 series surge arrester mainly applies at power line of AC 50Hz/60Hz, rated operational voltage 230V and 400V to limit instantaneous over-voltage (lightning induction and switching over-voltage).
• Prevent the danger of thunder strikes; protect the circuit safety, quick response, and good thunder protection effect.
• It makes the protected electrical device and parts lower one level at occasion of higher over-voltage category, and lower down the voltage further when applied at terminal to protect devices.
