This type of fuse contains a fuse wire in it, which carries the short circuit current safely for a given time period. During this period, if the fault is removed, then it does not blow off otherwise it will melt and remove the circuit from the electrical supply hence, the circuit remains safe. Features: It clears high as well as low fault currents. Do not deteriorate with age. Having high-speed operation. Provides reliable discrimination. Require no maintenance. Cheaper than other circuit interrupting devices with the same rating. Permit consistent performance Fusing operation is fast without Noise and Smoke Specification: Diameter : 22mm Current Rating: 2A,4A,6A,10A,20A Nominal Voltage: 500V Material: Ceramic Fuse Type: HRC Length : 50mm Package includes: 1 x HRC AR Ultra Rapid Industrial Fuses Bottle Neck Fuse
