如何选择GRL熔断器？五个小步骤教会你！
本文中GRL来教大家如何通过五个小步骤选择适合自己的熔断器，希望对各位工程师朋友有所帮助。
1.如何选择熔断器？
我们可以从应用场景、电压、电流等维度去选择适合的熔断器。
在电力分配领域，电流一般大于63A，通常使用交流NH系列熔断器；
在工业控制领域，熔断器一般起到保护支路的作用，电流较小，故推荐使用RT18系列熔断器；
在通讯领域，通讯柜一般应用到DC80V的电路中，推荐使用DC80V，NH00系列熔断器；
在新能源领域，常用电压为DC1000V/DC1500V，如应用到汇流箱中，推荐使用DNPVF1系列；如应用在集中式逆变器控制箱，推荐使用NHX系列。
2. 我们熔断器有哪些尺寸？
在圆柱系列中，有10*38，14*51，22*58，10*85，14*85型号。
3. 为什么要选择紫铜触头，而不是黄铜触头？
紫铜拥有比黄铜更好的导电性，采用紫铜触头，可以让产品温升更低，降低使用风险。
4. 为什么要采用一级高频陶瓷作为熔断器外壳？
在熔断器熔断前，在熔断器内部，过载电流会产生大量的热能，甚至会引发爆炸；相比一般陶瓷，高频陶瓷拥有更稳定的物理性能，避免产品发生爆炸、裂开等现象，使用更加安全。
5. 为什么要使用高纯度高硅石英砂？
在熔断器熔断时，高硅石英石保证熔断器在短时间内快速熔断，对电气元件起到更好的保护。
6. GRL的熔断器有哪些证书？
TUV、CE、CB
