Dual Power Automatic Transfer Switch Changeover CB Grade Micro Break ATS NLQ4‑125‑4P 400V

Feature: 1. SAFE PROTECTIVE COVER: This product has reasonable structure, small size, beautiful appearance, and has a protective cover, which makes the power supply safer and more reliable 2. ENSURE NORMAL LOAD: When the power supply fails (only test the normal A phase voltage and maintain the A phase voltage, only test the loss of voltage or phase loss), will automatically connect one or more load circuits from the power supply to another power supply to ensure normal power supply load. The power supply of the circuit ensures a good protection function 3. NOISELESS AND ENERGY SAVING: EPS fire fighting power interface, DC12 24V reliable, long distance double point, bring noiseless operation, energy saving, easy installation, simple operation, reliable and stable performance 4. COMPLETE PROTECTION FUNCTIONS: Come with short circuit protection, overload protection, under voltage protection, as well as fire protection, dual output and shutdown signal functions 5. WIDE APPLICATION: Widely used in the 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 4P Rated Voltage: 400V Rated Current: 125A Rated Frequency: 50Hz 60Hz Rated Short Circuit Current: 3kA Mechanical Life: Automatic: 3000 Times; Manual: 1500 Times Rated Insulation Voltage: 500V. Package List: 1 x Dual Power Automatic Transfer Switch1 x User Manual Note: 1. The maximum ambient temperature should not exceed 40 celsius , the minimum should not be lower than ‑5 celsius , and the average temperature within 24 hours should not be higher than 35 celsius .2. The altitude of the installation site should not be higher than 2000meter.3. When the maximum temperature reaches 40 celsius , the relative humidity of the installation site should not exceed 50percent ; when the temperature is the lowest temperature of ‑5 celsius , the relative humidity is higher, for example, if the temperature is 25 celsius , the relative humidity is 90percent . Special measures should be taken to deal with occasional condensation on product surfaces due to temperature changes.4. 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
