    Real quality challenge: According to the Quality Manager at a panel building LLC the following was concluded after testing 500 MCCBs: \u201cWe passed all of them through routine tests. However, regarding thermal trip intermittent failures we had 12 reject in the field after being installed.\u201d The reason why the thermal trip fail rates were missed at the test bench; delta\/variation were not tested since the test was conducted only at 25 degrees Celsius. An MCCB test bench isn’t a basic go\/no-go station but rather one that has additional responsibilities.
