Feature 1 2 Operation Modes: Dual power automatic transfer switch can be operated automatically or manually, the millisecond switching is uninterrupted, the structure is compact, the transmission is reliable, the installation and maintenance are convenient, and the service life is long. 2 Continuous Power Supply: When the normal power supply is abnormal, the backup power supply works immediately to ensure the continuity, reliability and safety of the power supply. 3 Rail Mounted: This automatic transfer switch is suitable for emergency power supply systems rated 110V 100A at 50 or 60Hz AC, which is specially designed for domestic rail installation and is specially designed for PZ30 distribution boxes. 4 Wide Application: This automatic transfer switch is used in various occasion where continuous power outages are not allowed, such as homes, shopping malls, factories, laboratories, farms, etc. 5 Reliable Material: The changeover switch is made of excellent flame retardant PC material, with excellent insulation, high temperature resistance, silver contacts anti aging, safe and reliable.Item Type: Dual Power Automatic Transfer SwitchMaterial: PC and silverModel: NLQ3 125 4PRated Current le: 100AInsulation Voltage Ui: AC690VRated Voltage Ue: AC110VFrequency: 50 or 60HzRated Control Voltage US: 110VAC 85% Us to 110% UsLevel: PC levelSpecification: 4PService Life: Electrical: 2000 timesMechanical: 5000 timesRated Short Circuit Current: 50kAFuse: RT16 00 63ARated Impulse Withstand Voltage: 8kVAuxiliary Circuit: 2 relays, each with two sets of contact capacity: AC110V50HZ le=5yTouch time: <50msOperation Conversion Time:<50msReturn Time: <50msClosing Time: <50ms Package List1 x Dual Power Automatic Transfer SwitchNote1. The maximum ambient temperature should not exceed 40C, the minimum should not be lower than 5C, and the average temperature within 24 hours should not be higher than 35 C. 2. The altitude of the installation site should not be higher than 2000m.3. When the maximum temperature reaches 40C, the relative humidity of the installation site should not exceed 50%; when the temperature is the lowest temperature 5C, the relative humidity is high, for example: the temperature is 25 C, and the relative humidity is 90%. Due to temperature changes, special measures should be taken to deal with occasional condensation on the surface of the product.
