3.2.2 Input Breaker Selection
Add a breaker or a power distribution box in the input wire of UPS, which matches with the power of
UPS, to isolate the mains. Consider the charging power of UPS and the transient current impact when
power on, the current of the selected breaker should be 1.5
～
2 times of the max. input current of UPS.
Besides, the selected breaker should be without the power leakage protection to avoid maloperation.
The distribution box is better to be made by the professional company. The selection of input breaker
