Features:  The multifunctional self-resetting dual display protector integrates over-voltage protections, under-voltage protections, over-current protections and integrated intelligent protector.   When the line has overvoltage, undervoltage and overcurrent faults, the product will automatically cut off the line.   When the line voltage or current returns to normal, the product will automatically resume normal power supplys after the delay time set by the user, no manual operation is required.  When the line appears instantaneous or transient overvoltage, the protector does not malfunction.  The line voltage is unstable or the power is suddenly cut off due to some factors, when the power recovers, the product will not connect to the power immediately. (This delay time is set by the user according to the local situation.)  The overvoltage value, undervoltage value, overcurrent value, circuit recovery time value and overcurrent protections reset time value of this product can be set by themselves.   Adjust the corresponding parameters according to local actual conditions and electrical usage conditions.    Note:   The line voltage should not be higher than 330VAC to prevents the product itself from being damaged due to excessive voltage. Please contact the manufacturer if a high power supplys is required in a specific situation.    Specifications:  Name: Self-resetting Dual Display Protector   Material: PC  Type: 40A, 63A, 80A (optional)  Ambient temperature: ≤+50℃ and ≥-10℃  Humidity: ≤60%  Rated voltage: 220VAC 50Hz  Transmission delay time after power-on and power-off: 5-300S adjustable (default 5S)  Boot delay time: 1-300S adjustable (default 5S)  Reset delay time after overcurrent protections: 30-300s adjustable (default 30s)  Product overcurrent delay timeL 6s (overcurrent time greater than this time will be confirmed as overcurrent and provide protections)  Own power consumption: less than or equal to 2W  Electrical machinery life: greater than or equal to 100,000 times  Item size: 35 * 65 * 85mm / 1.38 * 2.56 * 3.35in  Package size: 90 * 90 * 40mm / 3.54 * 3.54 * 1.57in  Package weight:  40A: 155g / 5.47ounce  63A: 165g / 5.82ounce  80A: 175g / 6.17ounce    Packing List:  1 * Self-resetting Dual Display Protector
