[ LINE IN ] IN: L N +--------------+ | [O/U Volt] | | [ 60A ] | +--------------+ OUT: L N [ LOAD OUT ]

If no “160” in amperage, replace with actual rating (e.g., 63A, 100A).

Many sellers do not include a physical manual in the box. If yours is missing, request a PDF from your seller, or use this enhanced guide to get started.

| Model Number | Typical Current Rating | Key Feature | | :--- | :--- | :--- | | | 1~63A adjustable | Over/under voltage & overcurrent protection | | TOVPD1-80-EC | 80A | Over/under voltage & overcurrent protection | | TOVPD1-100-EC | 100A | Over/under voltage & overcurrent protection |

Take the time to configure the device thoughtfully for your specific load—it will reward you with years of reliable, silent protection.

Do not change unless you understand local grid limits (e.g., never set Uover > 290V for 230V systems).
