(1)额定电压 熔断器长期工作时和分断后能够耐受的电压,其量值一般等于或大于电气设备的额定电压。 



(2)额定电流 熔断器能长期通过的电流,它决定于熔断器各部分长期工作时的容许温升。 


(3)极限分断能力 熔断器在故障条件下能可靠的分断最大短路电流,它是熔断器的主要技术指标之一。 


(4)弧前电流—时间特性。 


(5)I2t特性 当分断电流甚大时,以弧前电流—时间特性表征熔断器的性能已足够了,因为此时燃弧时间在整个熔断时间并不能忽略。又由于这时电流在20ms甚至更短的时间内就分断,若以正弦波有效值来表示它,则在分析其热效应方面也不够恰当,因此,要通过积分(∫t0 idt)来表示热效应,这就是I2t特性。通常,熔断器的保护性能在熔断时间小于0.1s时是以I2t特性表征的;在熔断时间大于0.1s时,则用弧前电流—时间特性表征的。 


(6)断开过电压 熔断器分断电路时因线路有电感所出现的、超过线路额定电压数倍的自感电势,它既会影响熄弧过程,也可能损坏线路和电气设备的绝缘。对于具有限流作用的熔断器,断开过电压相当高,对此尤应注意。
