  3. 3. NH Fuse Links Application Introduction The Sri Vaari Powers ® NH fuse link range uses the latest technology to provide class leading fuse link performance and reliable indication. With a unique patented Single/Dual indicator design capable of operating a micro switch for remote fuse indication, Powers Secure (PS) provides one of the most reliable solutions available. The range is fully compliant with IEC 60269 standards and complies with the dimensional requirements of DIN 43620 for ease of use. In order to help select the correct product for an application, Powers Secure (PS) provides the following application notes. Selecting the Correct Product Before making a fuse link selection the following information should be known about the system or circuit to be protected. Type of Application (Cable Protection / Motor Protection) For general applications or cable protection, the standard gG (general purpose) NH fuse link should be considered. For Motor protection applications, the aM (motor protection) NH fuse link should be considered. Motor Protection (aM) fuse links have partial range breaking ability and cannot clear low overload faults. Should only be applied to circuits also protected by a motor protection relay or where only high short-circuit faults could occur. Please note that misapplication of a fuse link can be dangerous, consult Powers Secure (PS) if there is any doubt over fuse link selection. System Voltage Powers Secure (PS) NH fuse links are available in three voltage ratings, 400V, 500V and 690V. These are maximum voltage ratings and should not be used where the system voltage could exceed the fuse link’s maximum rating. Full Load Current In accordance with IEC standards, Powers Secure (PS) NH fuse links are tested to carry full load current. The rated current of a fuse link should be equal or greater than the operational current of the circuit and equal or smaller than he continuous current carrying capacity of the conductor. The standard gG (general purpose) NH fuse link with a conventional fusing current of 1.6 times rated current will give assured cable protection against the effects of overcurrent.-3-
  4. 4. Non-Fault Overload Currents (motor inrush currents etc) To prevent nuisance operation of the fuse link, the fuse link rating selected for the application should take into account any non-fault overload currents. Please refer to the time-current curves in the catalogue. Possible Fault Conditions and Maximum Short-Circuit Current This information is essential in order to select the fuse link that would provide the best possible protection under all fault conditions. Powers Secure (PS) NH fuse links have a maximum breaking capacity of 100 & 120kA and should never be used on a system where the maximum short-circuit current exceeds this level. Please refer to the time-current curve in the catalogue. NH Fuse Links Application Time-Current Curves The time-current curve is probably the most useful piece of all fuse link data available. It allows you to determine how quickly the fuse link will operate under fault conditions and which fuse link will not operate under non-fault overload currents. To use the curve simply plot the prospective Root Mean Square (RMS) fault current along the X axis and draw a line vertically upwards from this point. Where this point intersects the fuse curve line, plot a line across to the Y axis for the relevant rating. The Y axis shows the nominal operating time for the fuse in seconds. Hence, it shows how quickly the fuse link will operate under different fault currents. The graph can be used to check if a fuse link can withstand an overload condition that is not considered to be a fault such as a direct-on-line (DOL) motor start. For example, if a motor starts and the inrush current is six times the full load current for 10 seconds, the exact point can be plotted onto the time-current curve. Any fuse link line lying to the right of this point will withstand the motor start current (allowing for a +/-10% tolerance on each fuse link curve). If the fuse link curve falls to the left of this point, then the fuse link will not withstand the motor start current and will inadvertently operate when the motor is started. In summary, the rule for time-current curves is that any point on or to the right of a fuse link curve would indicate the fuse link has operated in the given time. Any point to the left of the curve would indicate the fuse link has not operated.-4-
  5. 5. B Fuse ratingCut off current Peak Peak let through current Peak RMS let through Current RMS Prospective fault current A RMS Prospective fault current Cut-Off Curves The graph consists of an A-B line running diagonally from bottom left to top right, see drawing below. This is known as he none current-limiting line. Branching from this A-B line you can see each individual fuse link rating line running iagonally left to right. o read the graph, plot the RMS prospective fault current along the X axis. If this point only ntersects the A-B line then the prospective fault current is too low to benefit from the current-limiting effect of the fuse ink. However, if this point intersects the relevant fuse link line, plot a line across to the Y axis. This point on the Y axis shows the peak asymmetrical let-through current the fuse link will allow to pass before operating. The peak asymmetrical let-through current is the absolute worst case peak current the fuse link will allow to pass through, taking nto account the DC offset seen under short-circuit conditions and low power factor. The RMS let-through current is read from the graph sing the same procedure above. Instead of plotting he point of intersection with the fuse link current limiting line over to the Y axis, it should only be plotted as far as the A-B line. At this point, a line can be drawn back down to the X axis to show a RMS symmetrical value of let-through current. This is known as the “up, over and down method”.-5-
  6. 6. NH Fuse Links Application I2t Values I2t values are measured at the time of testing the fuse link at their rated breaking capacity and voltage. I2t is effectively the amount of heating energy the fuse link will allow to pass during fault clearing at high short-circuit faults. I2t values relevant for short-circuit faults cannot be calculated from the time-current or cut-off curves. The published I2t figures always show two values, pre- arcing/total clearing and are representative of the area under the first half cycle of the fault current. I2t values give a good representation of the speed of operation of a fuse link. A small I2t value would indicate a very fast-acting fuse link whereas a large I2t value would indicate a fairly slow operating fuse link. In all cases the total clearing I2t value of the fuse link must be smaller than the I2t value of the device to be protected in order for the fuse link to provide adequate protection against short- circuit faults. For fuse link discrimination (see definition of discrimination below) in distribution systems, the total clearing I2t value of the fuse link downstream should be less than the pre- arcing I2t value of the fuse link upstream. This ensures the smaller fuse link, in the system operates well before the larger upstream fuse link. NH Discrimination Power Secure (PS) ® NH fuse links are easy to use on distribution networks where discrimination between large and small fuse links are required. This can be achieved by applying a discrimination factor of 1 to 1.6 without the need to check the fuse link data. For example, by using a 100A fuse link downstream from the main 160A fuse link, in the event of a fault condition, the smaller 100A fuse link is sure to operate before the 160A fuse link, ensuring discrimination. DC Applications Power Secure (PS) NH fuse links can be used on DC applications. In all cases the fuse links can be used at half of their AC rating with a time constant of no more than 10mS. The time constant is the rate of rise of fault current and should be as close to a 50Hz AC half cycle as possible. Power Loss Every effort is made to ensure the power loss of the fuse link is kept to a minimum. Cooper Bussmann provides fuse links with some of the lowest power losses in the industry. Power loss of the fuse link is given off as heat and this should be taken into account when fitting fuse links into unventilated areas. It is preferable that a fuse link has good airflow around the body of the fuse link to ensure cool running and prevent nuisance operation of the fuse link due to thermal stresses.-6-
  7. 7. NH Dual Indicator System Catalogue • The pre-arcing value is the area under the first half cycle of fault current showing on the graph in yellow to the point just before an arc occurs within the fuse link. This is due to the element material being vaporized by the very high short-circuit current. • The total clearing I2t is the yellow and green area under the first half cycle from the start of the short-circuit current flow to the point where the fuse link has become an insulator, completely isolating the flow of current. The diagram here shows a representation of I2t during a half cycle of fault current. Time in Seconds Potentional Fault Current A – Pre Arc I2T A Current in amps B – Total clearing I2T.
