a）Ambient air temperature
Considering that high ambient temperature accelerates the aging of plastic parts, the
upper limit shall not exceed +40℃
Considering the excessively low ambient temperature changes the fit of structural
parts, the lower limit value is generally not less than -5℃. Considering the service
life of the circuit breaker, the average value of 24 hours is not more than +35℃.
b)
Note: ① The working conditions with the lower limit of -10℃ or -25℃ shall be
declared to the company when ordering.
② If the upper limit exceeds +40℃ or the lower limit is lower than -25℃, the user
shall negotiate with the company.
Installation location
c)
