Dual Power Automatic Transfer Switch Electrical Selector Switch for Office Buildings 230V

Feature: 1. Power Supply Detection: Composed of 2 miniature circuit breakers, a motor and mechanical rotating device,lifting device is used to detect power supply together with controller. When circuit is abnormal, controller makes logical judgment on test result, and turns on or off drive according to command, to ensure electrical loads safety and reliability 2. Guaranteed Power Supply: When the power supply fails one or more load circuits will be automatically connected from power supply to another power supply to ensure normal power supply of power load circuit 3. Complete Protection Functions: This dual power automatic transfer switch has short circuit, overload and undervoltage protection 4. Easy to Use: Good practicability, reasonable structure, small size, beautiful appearance, protective cover, safe and reliable power supply 5. Application: Widely used in installation and use of lighting circuits in office buildings, shopping malls, banks, stations, hospitals and high rise buildings with fire protection requirements Specification: Item Type: Dual Power Automatic Transfer Switch Model: NLQ4 125 2P Rated Voltage: 230V Rated Frequency: 50Hz 60Hz Rated Short Circuit Current: 3kA Mechanical Life: Automatic: 3000 Times, Manual: 1500 Times Rated Insulation Voltage: 500V Material: Plastic. Package List: 1 x Dual Power Automatic Transfer Switch 1 x User Manual Note: Installation environment conditions: 1. The highest ambient temperature is not more than 40 degrees C, the lowest is not lower than ‑5 degrees C, and the average temperature within 24 hours is not higher than 35 degrees C2. The altitude of the installation site should not be higher than 2000m3. When the maximum temperature reaches 40 degrees C, the relative humidity of the installation site should not exceed 50percent ; when the temperature is the lowest temperature of ‑5 degrees C, the relative humidity is higher, for example, if the temperature is 25 degrees C, the relative humidity is 90percent . Special measures should be taken to deal with occasional condensation on product surfaces due to temperature changes4. Low pollution level, no serious vibration and shock, no corrosive environment, no serious dust, no conductive particles and explosive dangerous substances, no strong electromagnetic interference
