The test conditions for operating the short-circuit breaking capacity are extremely harsh (primary breaking, secondary making and breaking). Since the Lv Pole Mounted Circuit Breakers continues to carry the rated current after the test (the number of times is 5% of the life span), it is necessary to verify not only the tripping characteristics and power frequency withstand voltage, but also the temperature rise.
