The measuring categories indicate in which application areas a measuring device can be safely used. The protection of a measuring device from a transient (=short-term, temporary) overvoltage is determined by the specification of the measurement category (overvoltage category) and the working voltage (nominal current to ground) e.g. CAT IV 600 V, CAT III 1,000 V. The IEC/EN 61010-1 standard subdivides measuring electric circuits into the following measuring categories: - CAT I: for measurements on electric circuits that are not directly connected to the mains. - CAT II: for measurements on electric circuits that are directly connected to the mains. - CAT III: for measurements in building installations. - CAT IV: for measurements at the source of the low-voltage installation. - The specification of the measurement category and the maximum nominal voltage determine the protection of the measuring device vis-à-vis transient (temporary) overvoltage. - Transient (temporary) overvoltages can occur due to a lightening strike in the distribution network or due to the switching on/off of large loads. - The following basic principle applies: the higher the measurement category and the higher the nominal voltage, the higher the protection of the measuring device vis-à-vis transient (temporary) overvoltage. - Protection against transient (temporary) overvoltage to 8 kV HSS bi-metal hole saw ø Soft VA- Cast Brass Alumi- mm steel steel steel nium 14 550 300 400 790 900 16 530 275 365 730 825 17 500 250 330 665 750 19 460 230 300 600 690 21 425 210 280 560 630 22 390 195 260 520 585 24 370 185 245 495 555 25 350 175 235 470 525 27 325 160 215 435 480 29 300 150 200 400 450 30 285 145 190 380 425 32 275 140 180 360 410 33 260 135 175 345 390 35 250 125 165 330 375 37 240 120 160 315 360 38 230 115 150 300 345 40 220 110 145 290 330 41 210 105 140 280 315 43 205 100 135 270 305 44 195 95 130 260 295 46 190 95 125 250 285 48 180 90 120 240 270 51 170 85 115 230 255 52 165 80 110 220 245 54 160 80 105 210 240 57 150 75 100 200 230 59 145 75 100 195 225 HSS bi-metal hole saw ø Soft VA- Cast Brass Alumi- mm steel steel steel nium 60 140 70 95 190 220 64 135 70 90 180 205 65 130 65 85 175 200 67 130 65 85 170 195 70 125 60 80 160 185 73 120 60 80 160 180 76 115 55 75 150 170 79 119 55 70 145 165 83 105 50 70 140 155 86 100 50 65 130 150 89 95 45 65 125 145 92 95 45 60 120 140 95 90 45 60 120 135 98 90 45 60 115 130 102 85 40 55 115 125 105 85 40 55 110 120 108 80 40 55 110 115 111 80 40 50 100 110 114 75 35 50 100 105 121 70 35 45 90 95 127 65 30 40 85 90 140 60 30 35 80 85 146 55 25 35 75 80 152 55 25 35 75 80 Data sheet for LED lamps Designation Art. no.
