Use in 40℃～60℃
Is it possible to use a circuit breaker in the ambient temperature of 40℃ or higher?
Answer
Operating ambient temperature is set to - 10℃ to 40℃. ( However, its average over a period of 24h does not exceed 35℃.) In the case that the ambient temperature exceed 40℃ temporarily, it is possible to use it up to 60℃ by reducing the load current. Derating factor is as follows.
*50℃: 0.9 or less *60℃: 0.7 or less
*50℃: 0.9 or less *60℃: 0.7 or less
