1、过载长延时保护
a) 过载长延时整定电流 Ir，容许偏差±3%。
b) 过载长延时整定时间 Tr，动作时间精度为±10%。
c) 过载保护按反时限特性进行，延时动作时间 tr=（2× Ir/I）2× Tr,符 合 IEC60947.2 中
7.2.1.2.4-b)-2)和8.3.3.7；
d)过载长延时具有热记忆功能，在产品脱扣后的 30min 内有效（需要 24V 辅助电源）
2、短路短延时保护

如：当 IR整定为 225A、Tr整定为 100s 时，当主回路电流为 2×225A 时，断路器将持续 100s 时后断
开主回路。动作时间精度为±10%。在过载电流下，断路器断开主回路的时间遵循以下公式：
t=(2×Ir/I)2×Tr（其中 I表示过载情况下，主回路实际电流值）
Notes: 1.Trindicates the operating time of the breaker when actual current is twice of IRsetting.
E.g.: when Irand TRare set as 225A and 100s respectively, when the current in main circuit reaches
2× 225A, the breaker will disconnect the main circuit after lasting for 100s. The time precision of
action is ±10%. Under the overcurrent, the time that the breaker disconnects the main circuit shall
follow the following format: t=(2×Ir/I)2×Tr(Of which, I stands for the actual current in the main circuit
under overcurrent.)
3.2.2.3 指示灯 Indicator light
（1）过载指示灯 Overload light
过载指示红灯恒亮时，表示实际电流超过了过载长延时整定电流值 IR的1.15 倍，处于过载状态，
并经一定的时间后断路器将断开。
过载指示灯快速闪烁时，表示在 3次脱扣动作仍未导致产品脱扣
Constant light of overload indicator indicates that actual current is more than 1.5 times of
overload long-time delay current setting IR. The breaker will break the circuit after certain duration.
When the overload indicator flashes fast，it indicates that the 3 trip has not caused the product
tripping
（2）电源指示灯 Power light
电源指示灯慢速闪烁时，表示正常运行
电源指示灯快速闪烁时，代表控制器自检或系统运行过程中检测到故障
When the overload indicator flashes slow，it indicates that the system is running normally
When the overload indicator flashes fast，it indicates that self checking of the controller or
failture detected during the system operation
注：两种指示灯应在每半年进行一次常规检验
