AOMEY-250-3P

AOMEY

Characteristics

Usage environment:
● The pollution level of AOMEY series products is 3 level.
● In the environment (industrial environment) defined by the IEC60947-1 and IEC60664-1 standards.
Ambient temperature:
● AOMEY can work continuously under normal environment and operating temperature conditions from -5 °C to +40 °C.
● If the working environment temperature exceeds 40 °C, the temperature derating coefficient table should be used in consideration, or contact us.
● The storage temperature is -20 °C to 70 °C.
● The altitude of the normal work installation site does not exceed 2000m.
● If you need to install at an altitude of more than 2000m, you must consider the change in dielectric strength and the drop in air temperature. You can refer to the altitude derating coefficient table for use, or contact us.

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.
