Glossary of Terms mpere The measurement of intensity of rate of flow of electrons in an electric circuit. n ampere is the amount of current that will flow through a resistance of one ohm under a pressure of one volt. mpere Rating The current-carrying capacity of a fuse. When a fuse is subjected to a current above its ampere rating, it will open the circuit after a predetermined period of time. mpere Squared Seconds, l 2 t The measure of heat energy developed within a circuit during the fuse s clearing. It can be expressed as melting l 2 t, arcing l 2 t or the sum of them as Clearing l 2 t. l stands for effective let-through current (RMS), which is squared, and t stands for time of opening, in seconds. rcing Time The amount of time from the instant the fuse link has melted until the overcurrent is interrupted, or cleared. reaking Capacity (See Interrupting Rating) Cartridge Fuse fuse consisting of a current responsive element inside a fuse tube with terminals on both ends. Class CC Fuses 600V, 200,000 interrupting rating, branch circuit fuses with overall dimensions of Ω 1 Ω. Their design incorporates a rejection feature that allows them to be inserted into rejection fuse holders and fuse blocks that reject all lower voltage, lower interrupting rating Ω 1 Ω fuses. They are available from Ω º through 30. Class G Fuses 480V,,000 interrupting rating branch circuit fuses that are size rejecting to eliminate overfusing. The fuse diameter is Ω while the length varies from 1fiΩ to 2 Ω. These are available in ratings from 1 through 60. Class H Fuses 250V and 600V, 10,000 interrupting rating branch circuit fuses that may be renewable or non-renewable. These are available in ampere ratings of 1 amp through 600. Class J Fuses These fuses are rated to interrupt a minimum of 200,000 ac. They are labelled as Current-Limiting, are rated for 600vac, and are not interchangeable with other classes. Class K Fuses These are fuses listed as K-1, K-5, or K-9 fuses. Each subclass has designated I 2 t and l p maximums. These are dimensionally the same as Class H fuses, and they can have interrupting ratings of 50,000,,000, or 200,000. These fuses are current-limiting. However, they are not marked current-limiting on their label since they do not have a rejection feature. Class L Fuses These fuses are rated for 601 through 6000, and are rated to interrupt a minimum of 200,000 ac. They are labelled Current- Limiting and are rated for 600Vac. They are intended to be bolted into their mountings and are not normally used in clips. Some Class L fuses have designed in time-delay features for all purpose use. Class R Fuses These are high performance fuses rated Ω º- 600 in 250V and 600V ratings. ll are marked Current Limiting on their label and all have a minimum of 200,000 interrupting rating. They have identical outline dimensions with the Class H fuses but have a rejection feature which prevents the user from mounting a fuse of lesser capabilities (lower interrupting capacity) when used with special Class R Clips. Class R fuses will fit into either rejection or non-rejection clips. Class T Fuses n industry class of fuses in 300V and 600V ratings from 1 amp through 1200. They are physically very small and can be applied where space is at a premium. They are fast acting and time-lag fuses, with an interrupting rating of 200,000 RMS. Classes of Fuses The industry has developed basic physical specifications and electrical performance requirements for fuses with voltage ratings of 600V or less. These are known as standards. If a type of fuse meets the requirements of a standard, it can fall into that class. Typical classes are K, RK1, RK5, G, L, H, T, CC, and J. Clearing Time The total time between the beginning of the overcurrent and the final opening of the circuit at rated voltage by an overcurrent protective device. Clearing time is the total of the melting time and the arcing time. Current Limitation fuse operation relating to short circuits only. When a fuse operates in its current-limiting range, it will clear a short circuit in less than Ω cycle. lso, it will limit the instantaneous peak let-through current to a value substantially less than that obtainable in the same circuit if that fuse were replaced with a solid conductor of equal impedance. Dual Element Fuse Fuse with a special design that utilizes two individual elements in series inside the fuse tube. One element, the spring actuated trigger assembly, operates on overloads up to 5-6 times the fuse current rating. The other element, the short circuit section, operates on short circuits up to their interrupting rating. Electrical Load That part of the electrical system which actually uses the energy or does the work required. Fast cting Fuse fuse which opens on overload and short circuits very quickly. This type of fuse is not designed to withstand temporary overload currents associated with some electrical loads. Fuse n overcurrent protective device with a fusible link that operates and opens the circuit on an overcurrent condition. High Speed Fuses Fuses with no intentional time-delay in the overload range and designed to open as quickly as possible in the short-circuit range. These fuses are often used to protect solidstate devices. Inductive Load n electrical load which pulls a large amount of current an inrush current when first energized. fter a few cycles or seconds the current settles down to the full-load running current. Interrupting Capacity See Interrupting Rating Interrupting Rating (reaking Capacity) The rating which defines a fuse s ability to safely interrupt and clear short circuits. This rating is much greater than the ampere rating of a fuse. The NEC defines Interrupting Rating as The highest current at rated voltage that an overcurrent protective device is intended to interrupt under standard test conditions. Melting Time The amount of time required to melt the fuse link during a specified overcurrent. (See rcing Time and Clearing Time.) NEC Dimensions These are dimensions once referenced in the National Electrical Code. They are common to Class H and K fuses and provide interchangeability between manufacturers for fuses and fusible equipment of given ampere and voltage ratings. Ohm The unit of measure for electric resistance. n ohm is the amount of resistance that will allow one ampere to flow under a pressure of one volt. 231
