熔断器是一种结构简单、使用方便、价格低廉的保护电器。熔断器主要用作电路的短路保护和过载保护,也可兼作电源隔离开关使用。目前,常用的低压熔断器有:RC_1系列插入式熔断器,RM_7、RM_(10)系列无填料封闭管式熔断器,RL_1系列螺旋式熔断器和RTO系列有填料管式熔断器。
Fuse is a simple structure, easy to use, low cost protection appliances. Fuse circuit is mainly used for short circuit protection and overload protection, but also doubles as a power supply isolation switch. At present, the commonly used low-voltage fuses are: RC_1 series plug-in fuses, RM_7, RM_ (10) series of fillerless closed tube fuses, RL_1 series of spiral fuses and RTO series filled tube fuses.
