11. TD160/TS250 -40℃ Verification of Temperature Correction- Susol MCCB TS250 Temperature correction at -40℃ was verified in accordance with IEC60068-2-1 standard, test of operation characteristic with 105~130% over current.

- Correction ratio were calculated in order to implement over current test of TS250 at -40℃.The test was successful and we have selected final correction ratio based on the test result.

- First temp. correction increase ratio (based on room temp.) : -0.5 %/℃(-40 ℃ correction ratio 140%)

- Second temp. correction increase ratio (Finalized) : -0.9 %/℃(-40 ℃ correction ratio 172%)

- Since correction ratio of TS250 and TD160 are identical at room temperature, TD160 is also tested with TS250 correction ratio. As a result, no problem found in over current test.

- No problem found in over current test of every ampere frame at min/max rated current.

* IEC60068-2-1 test standard

- Specific heat dispersion MCCB sample was used in the test- 96 hours of full saturated time, IEC Standard, was applied to the test

* Tester Opinion- It seems correct to keep the surrounding temperature constant and carry on test after the product temperature stabilized in surrounding temperature.-It is found that sustainment time after stabilization does not affect the characteristic of product.-The main purpose of assignment is not to develop product for extremely low temperature but to develop correction ratio of surrounding temperature in order to check Susol MCCB’s over current characteristic at -40℃

22. TD160/TS250 Temperature Correction Table

- The final correction ratio was selected between the two linear section of temperature rise ratio 0.5 at the room temperature and 0.9 at the extremely low temperature

- Correction ratio of existing product at room temperature (10~40 ℃) is same and correction ratio at low temperature increases in the shape of exponential function

(Temperature correction ratio of OQC outgoing inspection standard and CB construction data is clearly stated between 10~40 ℃)

5. Susol Electronic MCCB -40℃ 200% Over Current Test- 200% over current test of ETS, ETM, OCR A type was implemented at -40℃and no problem found.- TS1600 was not able to apply 200% over current test due to not enough size of constant

temperature oven and other facilities. 0.5% ground fault operation test was implemented instead.- TS1600 OCR PS type was excluded from the test due to below standard specification of LCD parts.

6. Conclusion

- -40℃ Correction ratio was selected for all AF of Susol MCCB and verified 105~130% over current characteristic in accordance with IEC60068-2-1 standard.

- Correction ratio of Trip parts at -40℃ was verified through Design of experiment and additional research of core technology regarding designing correction ratio to surrounding temperature is necessary.

- This test covers only 105~130% over current characteristic at -40℃. Mechanical endurance was not able to be tested due to not enough facility in PT&T.
