what is ambient temperature for compact NSX (operational and storage) ?

.compact NSX circuit breakers may be used between -25°C and +70°C. For temperatures higher than 40°C(65°C circuit breakers used to protect motor feeders), devices must be derated

.Circuit breaker should be put into service under normal ambient, operating-temperature condition. Exceptionally, the circuit breaker may be put into service when the ambient temperature is between -35°C and -25°C

.The permissible storage-temperature range for compact NSX circuit breakers in the original packing is -50°C and +85°C
