AOMEY-250-3P/4P Electronic LIQUID Crystal,Products,ZHEJIANG ZHONGAO ELECTRIC CO.,LTD.

Humidity：

Need to meet during normal work:

● When the ambient air temperature is +40 °C, the relative humidity of the atmosphere cannot exceed 50%. If the temperature is lower, it can be used under higher relative humidity.
● The average monthly relative humidity of the wettest month is 90%.
● Need to consider the effect of condensation on the product's performance.
Reliable contact indication with isolation function：
● AOMEY series molded case circuit breakers are in line with the isolation defined in IEC60947-2.
● The isolation position corresponds to the O (OFF) position.
● Only when the contact is really opened, the operating handle can indicate the "OFF" position.
● After testing, the isolation function is safe and reliable.
Protection level：
● Circuit breaker body: IP protection grade is IP20.
