ABB快速熔断器250A 690V  快熔OFAA1GG250 熔芯250A 保险丝250A 

 

    ABB熔断器分为500V和690V两种，都是为了满足现代化工业和电力系统要求设计的，
具备了分断*高短路电流的能力。400V熔断器的短路分断能力可超过100 kA。
另外，690V熔断器分为双显和单显熔断器，双显全系列产品设计及工艺制造方法已获得
10项专利，双重保障知识保证不需要借助任何仪器准确及时检测系统故障，提供供电可
靠性。分断能力达到80KA。快速熔断器设计和测试按照IEC60269标准进行。额定电压达到690VAC，电流20-1000A，分断能力高达200KA RMS Sym

    出色的限流能力
熔断器拥有出色的限流能力，配合标准容量的电缆和元器件便可确保接触器和继电器的正常运行，而截断电流值非常小。配合类型2 表示电路中的所有元件必须在短路发生后仍可继续使用，熔断器有效保证了这一点，且不需要额外扩容。
    熔断器如何限流
为了避免危险，并对设备和电路造成的伤害，必须以*快的速度分断短路电流。由于短路电流产生的温升非常快，会导致设备的瘫痪。而熔断器可对温升迅速反应，并且其限流能力很强。熔断器中的石英砂阻隔了短路飞弧产生的高温，与此同时熔体由于温度上升很快而熔断。
熔断器系统的维护成本很低。熔断器本身可承受很高的短路电流冲击，每当熔断后，更换的只是熔断器本身。由于更换熔断器非常简单迅速，使用熔断器做保护的系统可减少工厂的断电时间，并降低维护成本。
