Feature 1SAFE FLAME RETARDANT: PC flame retardant material, with overvoltage protection, undervoltage protection and voltage display(voltage measurement), the use is more safe and reliable 2PROTECTION AGAINST DAMAGE: Designed for AC 50Hz 60Hz circuit, the maximum rated current is 63A, to protect you and the equipment from overvoltage, undervoltage, surge, leakage, lightning and other injuries 3DETECTION BEFORE CLOSING: Automatic reset power supply protection switch to monitor the circuit, in the occurrence of overvoltage, leakage, overcurrent and other failures will not close; Automatically save trip information, including time, type (cause), voltage, current, leakage current and other trip information, facilitate fault analysis 4DELAY POWER ON FUNCTION: When the fault recovers to normal, 3060 minutes delay protection, automatic power on(no manual); Intelligent leakage identification: automatic detection of voltage is normal before closing, N line is connected, failure will never close 5WIDELY APPLICABLE: Suitable for communication base station, repetor station, video surveillance, security city, cable TV, digital TV, network switch, optical terminal machine, meteorological telemetry station, seismic detection station and other electrical equipment under various conditionsItem Type: Over Under Voltage ProtectorMaterial: PCRated Voltage: AC230V 50HZ (AC220V available)Rated Current: 1-63ALeakage Protection Function: 1, Leakage Protection Setting Range: 10 mA-99mA2, Leakage Protection Action Time: Less than 0.1 secondsOvercurrent Short Circuit Protection Function: 1, Setting Range of Overcurrent Protection: 1A-63A2, Overcurrent Protection Action Time: 1-3 Seconds(a protector with a rated current of 63A as an example)3, Short circuit protector current 3 times rated current4, Short Circuit Protection Action Time: 0.1 secondsAdjustable Function: Current 1-63A(adjustable) can be set according to the place of electricity use1, Over and Under Voltage Value Adjustable Range: Voltage 250V-300V2, Undervoltage Adjustable Range: 150V-190V3, Current Adjustable Range: 1-63A4, Leakage Value Adjustable Range: 10MA-99MA5, Delay Protection Time Adjustable Range: 1-60SDelay Protection Function: When the fault recovers to normal, 30-60 minutes delay protection, automatic power(no manual)Family Setting Value Reference: The current value is set to the same amperage as the main switch. If reclosing is used, the main switch is set to 63AThe leakage value is set to 30 mAThe Value of Overvoltage And Undervoltage: 270V-280VThe Undervoltage Value Set To: 170VWorking Environment: Temperature: -20 ~ 55Storage Temperature: -45 ~ 80Humidity: 95%RhAtmospheric Pressure: 70kPa ~ 106kPaProtection Function: Overvoltage Protection: When the voltage between the live line and the tail line at the input end is higher than the set value, the switch trip protection.Low Voltage Protection: When the input live line and neutral line voltage is lower than the set value, trip protection.Overcurrent Protection: When the actual current is greater than or equal to 1.15 times the rated current for 3 seconds, the switch trip protection.Leakage Protection: When the leakage current exceeds the set value or electric shock occurs, the automatic reclosing switch will be disconnected within 0.1 seconds to ensure your safety.Automatic Disconnect: The switch will be automatically disconnected when the circuit is disconnected, and the switch will be automatically registered when the normal power supply is detected.Automatic Recovery: If the fault occurs, the fault will be automatically lost after a certain period of time. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Over Under Voltage ProtectorNote1. The switch cannot be used as the main switch. Install microbreaker in front of switch as overload short circuit fixture.2. Please adjust the current after installation.3. This product has no isolation function. Disconnect the front switch before repairing the circuit.
