When the overload indicator is always on, it means that the actual current exceeds 1.15 times of the overload
long delay setting current value Ir, which is in an overload state, and the circuit breaker will be disconnected after
a certain time.

3.3.2 控制器整定值
(1)过载长延时保护 (见表 5)Overload long-time delay protection (Table 5)
过载长延时保护基于电流的真有效值(RMS),用来对过负荷进行保护。
Overload long-time delay protection is basic on the RMS of current, which is used to protect the load.
