What is the temperature range for electric metering components if it is not stated on the device?

The correct choice indicates a temperature range of -20° C to 50° C for electric metering components when no specific range is stated on the device. This range is widely accepted as a standard operating temperature for many electrical and electronic devices, ensuring optimal performance and reliability under typical environmental conditions.

In practical applications, operating outside this temperature range could jeopardize the accuracy, functionality, and longevity of the metering components. Therefore, the -20° C to 50° C range acknowledges the variations in conditions that these devices might face while still ensuring accurate metering results and operational safety.
