How many degrees can the energy meter case withstand

The temperature range of the watt-hour meter case depends mainly on its material and design. ‌


Temperature range for different types of watt-hour meter cases

smart energy meter case ‌ : The use of class II protective insulation envelope, in the high temperature environment of 90 ° C should not be deformed, at 650 ° C ±10 ° C temperature does not support combustion, can be extinguished ‌12.

ordinary watt-hour meter case ‌ : the working temperature range is -25℃ to 55℃, the working limit temperature range is -40℃ to 70℃, the storage and transportation limit temperature range is -40℃ to 70℃‌3.

Selection criteria for energy meter case materials

The case of the energy meter is usually made of flame-retardant PC/ABS material, which has excellent flame retardant properties and high temperature resistance. It can maintain good physical and mechanical properties under high temperature environment to ensure the long-term stable operation of the watch case. Flame retardant PC/ABS material has high flame retardant, high temperature resistance, excellent mechanical properties and chemical resistance, making the watch case can work safely and reliably in a variety of harsh environments ‌


In summary, the tolerance temperature of the smart watt-hour meter case is 90 ° C, while the tolerance temperature of the ordinary watt-hour meter case is -40 ° C to 70 ° C. Choosing flame-retardant PC/ABS material as the manufacturing material of the watch case has obvious advantages, which can maintain good physical and mechanical properties under high temperature environment.
