1. Timed Overcurrent Protection, The overcurrent value varies at different times. For example, you can set the current value to 15A at 9:13 AM and the overcurrent value to 5A at 6:05 PM. 2. Undercurrent Protection, For example, you can set the current value to 10A and the action time to 20 seconds. When the load is below 10A for more than 20 seconds, the protector turn off the load. 3. Bidirectional Measurement, Total Energy (KWh) (Positive kWh + Negative kWh) Function: 1. Undervoltage protection: 80V-210V (adjustable) (default: 175V) 2. Overvoltage protection: 120V-300V (adjustable) (default: 275V) 3. Overcurrent protection: 1A-63A (adjustable) (default: 63A) 4. Undercurrent protection: 1A-63A (adjustable) (default: disabled) 5. Reconnection time (time delay): 10s-90s (default: 30s) 6. Leakage protection: 10-99mA 7. Power display range: 0-99999.9 kW/h 8. Voltage Meter 9. Ammeter 10. Energy Meter 11. Timer Note: This device has a memory function. When the power is cut off, the device can remember the kWh value, overvoltage, undervoltage, and overcurrent.
