Usage: G2R-63 type automatic transfer switch is a PC-level infrequently used transfer switch, with dual power supply design (A is commonly used, B is standby), and is suitable for systems with AC 50-60Hz and rated current 6A-63A. The main function of the automatic transfer switch is that if the main power supply (public power supply A) fails, the ATS will automatically switch to the backup power supply (backup power supply B) to continue working (switching speed ;50 milliseconds), which can effectively solve the trouble caused by power outages. Features: 1. Flame-retardant shell, simple wiring, small size, simple installation, multiple protections, and durable. 2. Driven by an excitation type electromagnet, the conversion speed is extremely fast, with millisecond level fast switching. The conversion working time is less than 50ms 3. The flame-retardant shell is used, which can withstand extreme environments, has strong adaptability and reliable operation. 4. The switch is designed with common power supply, backup power supply, load power supply power-on indicator light, and the switch status is clear. 5. Modular structure design, same-side wire entry, convenient wiring, total weight less than 0.4KG, compact structure, small size, support 35mm installation, and can be used in household distribution boxes. 6. The product has an arc extinguishing system inside, which can quickly cool down and extinguish the arc. The outer shell is made of fireproof material, which is free from fire, safe and secure.

The temperature range of the working environment is -5°C-+40°C, and the average temperature within 24 hours should be lower than +35°C 2. The temperature range of the storage environment is -25°C-+55°C, and it can reach +70°C in a short period of time (within 24 hours) 3. The altitude of the installation site should be lower than 2000 meters. 4. When the ambient air temperature is +40°C. The higher the relative humidity, the lower the temperature. For example: when the wettest month is +20°C, the monthly average maximum relative humidity can reach 90% in that month. Appropriate measures should be taken to prevent condensation caused by temperature changes. 5. Pollution degree 3 (conductive pollution or dry non-conductive pollution becoming conductive due to condensation). 6. The protection level of the ATS chassis is IP30.
