YCQ6B series automatic transfer switch is applicable to 3 phases 4 wires dual powergrid with AC 50Hz, rated voltage 400V and rated current up to 63A. When a power goes wrong, it will automatic connect one or several load circuits from this power to the other power automatically, to ensure normal power supply of load circuits. And it keeps the original mini circuit breakers' overload and short circuit protection functions. The product is suitable for industrial, commercial, high-rise and civil residential areas.
1. Ambient air temperature
Limit of temperature: -5℃~+40℃.
The average no more than +35℃ within 24 hours.
2. Transportation and storage
Limit of temperature: -25℃~+60℃,
The temperature can be up to +70℃ within 24 hours.
3. Altitude ≤ 2000m
4. Atmospheric condition
When the temperature is +40℃, the air relative humidity should not exceed 50%, only under lower temperature can allow for higher relative humidity. If the temperature is 20℃, the air relative humidity could up to 90%, Special measures should be taken for occasional condensation due to humidity changes.
