Instructions for use in abnormal temperature environments
- The GB/T 14048.1 standard specifies the normal working environment temperature of the product, and its use within the normal working environment temperature range has no significant impact on product performance.
- When the working environment temperature is higher than+40 ℃, it is necessary to consider that the allowable limit temperature rise of the product must be reduced. The rated working current must be lowered, and the number of contactors installed in standard components must be reduced. Otherwise, it may damage, shorten the product life, and reduce work reliability, and also affect the product’s operating range; When the working environment temperature is below -5 ° C, it should be considered that the grease used for insulation and lubrication will freeze at low ambient temperatures, leading to product malfunction. Therefore, manufacturers and users need to negotiate for design or use.
- The following table shows the correction factors for the rated working current when the working environment temperature exceeds+55 ℃ and the rated working voltage remains unchanged.
| Temperature(℃) | 55 | 60 | 65 | 70 |
| correction factor | 1 | 0.93 | 0.875 | 0.75 |
