The short-circuit protection of thermal-electromagnetic type AC Lv Pole Mounted Circuit Breakers adopts a magnet system. It is used for the rectifier circuit (DC) after filtering. The original AC set current value needs to be multiplied by a coefficient of 1.3. The short-circuit protection of the full electromagnetic type is the same as the thermal electromagnetic type.
