2 WEG ar fuses are available from 20 to 1000 A and were desined accordin to IEC and dimensional requirements of DIN For short circuit protection of semiconductors / electronic equipment up to 690 Vac Available sizes NH rane - sizes 00, 1, 2 and 3 General Data Fuse type: Hih Speed (ar), Square Body (NH) Max. Application Voltae: 690 Vca 50/60 Hz Short Circuit Breakin Capacity: Vca Standard: IEC Certification: Note: WEG s ar and L/G NH rane fuses may be mounted in the same fuse base. Fuse Functionin In short circuits, the fuse element fuses, openin the electric circuit and interruptin the current flow. The ar fuses are not desined to be used in short overloads, because they may act inappropriately. Durin the short circuit, the fuse will limit the prospective short circuit current, accordin to the picture below: I I p I c I c : Current limited by the fuse t s : Pre-arc time t L : Arc time I p : Prospective short circuit current t s t L t 2

18 Appendix 1: WEG ar hih speed fuses sizin criteria Fuse Sizin The sizin of is subject to many variables, but two of them are the most sinificant: I²t and rated current. On the next pararaphs you will find three different suestions on how to size WEG ar fuses dependin on the load type. Without Overloads For applications without overloads, the rated current of the load should be at least 20% lower than the rated current of the fuse. The current reduction factor of the fuse base must also be taken into consideration and if it is lower than 0.8 (see pae 14), the current reduction factor must be fuse base reduction factor. Also, the I²t of the fuse must be equal or lower than the maximum allowed I²t for the protection of the semiconductor. Example: A diode bride with rated current I N of 250 A, I²t of 120 ka²s, rated phase voltae 690 Vac and without overloads. The fuse current should be: I F I N / 0.8 = A size NH1 fuse of 315 A should be enouh, but when mounted on the fuse base BNH1, the reduction factor is 0.75, and the maximum allowed current is only 236 A. Therefore, in this case the riht fuse is the 400 A NH1. When mounted on the fuse base it has a rated current of 280 A, which is hiher than the rated current of the diode bride. The I²t of the FNH1-400K-A fuse is Vac, and is lower than the I²t of the semiconductor, so the short circuit protection is uaranteed. Parallel Association If the current of the load is too hih, or if the I²t of the selected fuse is larer than allowed, parallel fuse association can be used, takin into consideration these restrictions: In addition to meetin the above specifications, the fuses connected in parallel must have the same characteristics, meanin that they must have the same size and rated current in order to avoid load unbalance, and the cable bars must have the same lenth to match the circuit impedance. The I²t value of the fuse association must be lower than the maximum I²t of the semiconductor and is calculated by: I²t // = I²t x n² where: I²t // is the I²t value of the parallel fuse association; I²t is the I²t value of the individual fuse, adjusted for the applied voltae (see pae 13); n is the number of fuses connected in parallel. Lon Duration Overloads Hih speed fuses must not be submitted to lon duration overloads above the AA line, presented on the Time vs. Current curves on paes 5 to 8. When lon duration overloads are unavoidable, the sizin of WEG ar fuses must be done considerin the overload current as the rated current of the system. Then the fuse rated current must be calculated the same way as on the Without Overloads pararaph. Cyclical Overloads Cyclical overloads are reular or irreular variations where the load current becomes hiher than the system rated current for a few seconds, but, bein enouh to raise the temperature of the fuse elements, causin thermal fatiue on its constrictions. Equipments that contain semiconductors and, consequently, hih speed fuses for short circuit protection, are frequently submitted to repetitive (or cyclic) overloads, especially when startin electric motors. Under this condition, the temperature of the elements of the fuse rises and, dependin on the number of overloads per time interval, this temperature may stress these elements or even reach the fusin temperature. This may cause the fuse to act inappropriately. To avoid the consequences of cyclic overloads, WEG ar fuses should, preferentially, be sized so that its current on the Time vs. Current charts of paes 5 to 8 is hiher than the overload current multiplied by the factors shown on the table below, and for the same duration. How many times the fusin current ar fuse size must be hiher than the overload current, for the same overload period Example: A semiconductor with 150 A of rated current where there are frequent overloads of 450 A with 5 s duration. For a NH00 fuse, the NH00 Time vs. Current curves on pae 5 should be used to search for a fuse that won t act at 2 x 450 A (900 A) in 5 s. In this case, the lower rated current found is 250 A. For fuses sizes of 1, 2 and 3 the same steps are made, but with a current 2.5 times hiher than 450 A, in this case 1125 A. For this current, all three fuse sizes have rated current of 400 A. The I²t of the selected fuses adjusted for the applied voltae, must be lower than the maximum allowed I²t for the protection of the semiconductor. In cases where it isn t possible to find a fuse that satisfies both the overload current and the I²t of the semiconductor criteria, there are two choices: - Fuse parallel association: divide the multiplied overload current (2 or 2.5 times the overload) by the number of fuses in parallel and repeat the method showed on the example above, with the I²t of the parallel association recalculated usin the equation shown on the Parallel Association pararaph. - Specify the larest fuse current that satisfies the I²t criteria, but perhaps not the overload. In this case the fuse may be subjected to some overload, which in time can cause the 18

19 Appendix 1: WEG ar hih speed fuses sizin criteria fuse to act inappropriately. This time period depends on the application, overload current, number of overloads per hour, duration of the overload, ambient temperature, ventilation, cable sizes and many other factors. The objective here is to protect the semiconductor in prejudice of the fuse. Several times this is a less expensive solution, as showed on the example 3 below. Summary Without Overloads 1. I F I N / If the current reduction factor of the fuse base is lower than 0.8, use the reduction factor of the fuse base, so I F x CRF Fuse Base I N And: 3. I²t F@Applied Voltae = I²t F@690 x MF 4. I²t F@Applied Voltae < I²t Max Allowed Where: CRF Fuse Base : Current Reduction Factor of the Fuse Base, on pae 14 MF: Multiplication Factor of the Total I 2 t Variation vs. Applied Voltae chart on pae 13 Lon Overloads 1. I N = I OL 2. Use the steps of the sizin without overloads Cyclic Overloads 1. I F@OL Time I OL x 2 (size NH00) or 2.5 (sizes NH1, 2 and 3) on the Time vs. Current charts And: 2. I²t F@Applied Voltae = I²t F@690 x MF 3. I²t F@Applied Voltae < I²t Max Allowed Parallel Association 1. Parallel fuses must be of the same size, rated current, and the system cables and bars must be of the same size and lenth to match the impedances. 2. I²t // = I²t x n² Sizin Examples Example 1: Sizin WEG ar fuses to protect a rectifyin bride with the followin characteristics: Maximum supported I²t: 80 ka²s Line voltae: 500 Vac Constant load Rated load current: 100 A Overload current: 200 A Overload duration: 5 min, a few times a day. Since overload duration is very lon, the overload current will be considered as the rated current of the system. The fuse current should then be: I F I N / 0.8 = 200 / 0.8 = 250 A In this case we select a size NH00 fuse of 250 A. This fuse when applied on a BNH00 fuse base has a reduction factor of 0.8, meanin that the rated current of the fuse mounted on this fuse base is 250 x 0.8 = 200 A, which matches the rated current of the rectifyin bride (it should be larer or equal to the rated current of the system). Next, the I²t must be analyzed in order to uarantee short circuit protection. The I²t of the 250 A NH00 fuse is Vac and the voltae applied on the fuse is the phase voltae: V F = 500 / 3 = 289 Vac Usin the Total I²t Variation vs. Applied Voltae chart on pae 13, we find a multiplication factor of approximately 0.49 for 289 Vac. Therefore, the adjusted I²t of this fuse is = x MF = x 0.49 = 48.4 ka²s, which is lower than the maximum allowed I²t of the semiconductor, 80 ka²s. Conclusion: The chosen fuse FNH00-250K-A mounted on the fuse base BNH00 will protect the rectifyin bride aainst short circuits. Example 2: Sizin WEG ar fuses to protect a CFW11 VSD with the followin characteristics: Rated current: I N = 370 A Maximum supported I²t: 414 ka²s Maximum I²t of the fuse: 0.75 x 414 = ka²s Line voltae: 480 Vac Overload of 1.1 x I N on the start for 60 s, up to 6 times per hour Because there is a cyclic overload, the criterion used is the one showed on the Cyclical Overloads pararaph. For a size NH00, the overload current is multiplied by 2, resultin in 814 A. With this current, on the FNH00 Time vs. Current chart on pae 5, at 60 s, there is no fuse available. For fuse size NH1, the overload current is multiplied by 2.5, resultin in A. On the FNH1 Time vs. Current chart on pae 6 with this current and 60 s, there is also no fuse available. Finally, for fuse size NH2, with the overload current multiplied by 2.5 ( A) at 60 s on the FNH2 Time vs. Current chart on pae 7, we find that the 630 A fuse is above this point, uarantyin that the fuse won t act inappropriately durin the start. This fuse, mounted on the fuse base BNH2, has a rated current of 441 A, which is larer than the rated current of the VSD (370 A) and the overload current (407 A). Therefore, with this method, because of the fuse bein oversized to withstand the startin current, there is no need to use the de-ratin of the fuse base. Next, the I²t of the fuse must be compared with the maximum allowed I²t of the semiconductor. The I²t of the NH2 630 A fuse at 690 Vac is A²s, but there is the need of adjustin it with the applied voltae. For a line voltae of 480 Vac, the phase voltae on the fuse is: V F = 480 / 3 = 277 Vac 19

20 Appendix 1: WEG ar hih speed fuses sizin criteria Usin the Total I²t Variation vs. Applied Voltae chart on pae 13, we find a multiplication factor of approximately 0.48 for 277 Vac. Therefore, the adjusted I²t of this fuse is: = x MF = x 0.48 = ka²s, which is lower than the maximum allowed I²t of the fuse, ka²s. Conclusion: The chosen fuse FNH2-650K-A will protect the rectifyin bride aainst short circuits and may be mounted on the fuse base BNH2. Example 3: Sizin WEG ar fuses to protect a SSW06 Soft-Starter with the followin characteristics: Rated current: I N = 312 A Maximum supported I²t: ka²s Line voltae: 575 Vac Overload of 3 x I N on the start for 30 s Because there is a cyclic overload, the criterion used is the one showed on the Cyclical Overloads pararaph. When searchin for a sinle fuse usin this method, the conclusion is that there isn t a fuse that satisfies both Current and I²t conditions. Then, the first alternative is parallel fuse association. With fuses in parallel, the current used on the Time vs. Current charts is 2 times the overload current for size NH00, or 2.5 times the overload current for sizes NH1, 2 and 3, divided by the number of fuses in parallel. So, for two NH2 fuses the current used on the correspondin chart is 312 x 3 x 2.5 / 2 = 1170 A. The fuse found is the NH2, 500 A. The adjusted I²t of a sinle fuse, in phase voltae of 332 V (575 V / 3) is A²s. Then, the total I²t of the parallel association is: I²t //@332Vac = x n² = 310 ka²s, which is larer than the maximum allowed I²t (178.5 ka²s), so it won t protect the Soft-Starter. If we continue to search for a fuse association, like different sizes with 2 fuses, or other combinations with different number of fuses, the final result is: 6 fuses in parallel per phase, size NH00, 125 A, with a result of 750 A. In most applications, a total of 18 fuses and 18 fuse bases (6 fuses and 6 fuse base per phase) demand too much space in the electric panel and cost too much assembly time and money. Since the main objective is to protect the semiconductor (Soft-Starter), not the fuse, the recommended WEG ar fuse for this case is the FNH3-710K-A, as its current is closest to the total current of the association (750 A) that also satisfies the I²t criterion (I²t of the fuse in 332 Vac is ka²s). Dependin on the application, the number of starts per hour, overload current, rated voltae, ambient temperature and many other factors, the fuse may act inappropriately, but this is a less expensive solution than 6 fuses per phase in many ways and will uarantee short circuit protection for the Soft-Starter.
