Edison Fuses

Current limiting fuses cut off a short-circuit current in less than one-half cycle, before it reaches its total available value. If not limited, short-circuit currents can reach levels of 30,000 or 40,000 amperes or higher in the first half cycle after the start of the short-circuit, causing severe damage. Therefore, it is important that a protective device limit fault currents before they can reach their full potential level. Edison Class RK1, RK5 and L are current limiting fuses. 

Edison Class RK1 duel-element time delay fuses are recommended for AC power distribution mains, feeders and branch circuits for transformers and motors, as well as non-inductive loads such as heating and lighting. They offer ratings up to 600 A with superior current limitation, cycling and overload capabilities. 

Edison Class RK1 fast-acting fuses are recommended for general power distribution system use for main, feeder and branch circuits having a high percentage of non-inductive loads such as lighting and heating. They are physically interchangeable with other R class fuses and will replace Class K or Class H fuses in standard fuse clips. 

Edison Class RK5 duel-element time delay fuses are recommended for AC power distribution mains, feeders and branch circuits for transformers and motors, as well as non-inductive loads such as heating and lighting, where the available short-circuit current does not exceed 200,000 RMS symmetrical amperes. 

Edison Class L time-delay or LCU fast-acting fuses are recommended for high-capacity main, feeder or branch circuits in power distribution systems for special applications such as system upgrading and install ahead of network protectors.
