#TDG_4_ElectronicFuse.fm Page 9 Sunday, July 31, 2005 8:33 AM 229P / 230P Series 2AG Slo-Blo(R) Fuse RoHS Pb UL The fuses combine conventional overcurrent protection with the ability to withstand high-current, short-duration pulses. They meet demanding telecom requirements and comply with the short circuit requirements of UL 1459. An insulating sleeve option is available. For environmental and physical specifications and soldering parameters, see www.littelfuse.com. The 2AG Indicating Slo-Blo fuse instantly identifies itself upon opening by showing a discoloration of its glass body, eliminating guesswork and timeconsuming circuit testing.

The "P" suffix indicates that it is a lead-free, RoHScompliant device. These fuses provide the same performance characteristics as the 3AG counterpart while occupying one-third the space. #TDG_4_ElectronicFuse.fm Page 10 Sunday, July 31, 2005 8:33 AM 229P / 230P Series 2AG Slo-Blo(R) Fuse Surge Ratings Cartridge Part Number Axial Lead Part Number IPP 2x10 s @ 2500 V Amps IPP 10x160 s @ 1500 V Amps IPP 10x560 s @ 800 V Amps IPP 10x1000 s @ 1000 V Amps 0229.250P 0230.250P not rated 23 16.6 12.4 0229.350P 0230.350P not rated 34 25.8 19.3 0229.375P 0230.375P not rated 40 25.4 19 0229.500P 0230.500P not rated 60 37.7 28.2 0229.600P 0230.600P not rated 71 47.2 35.3 0229.750P 0230.750P not rated 91 65.5 49 0229.800P 0230.800P not rated 104 68.9 51.6 0229 001.P 0230 001.P not rated 130 88.6 66.3 0229 1.25P 0230 1.25P 500 162 118.1 100 Notes: * Fuses withstand 50 repetitions of a double exponential impulse wave at listed currents and voltages, except that the 229 1.25 / 230 1.25 fuse withstands 20 repetitions at 2x10 s @ 2500 V. * To order an indicating 2AG Slo-Blo fuse, add an `S' at the end of the part number (for example, 230 001S). * To order fuses to DSCC Drawing #87108, change 229 to 290 and 230 to 291.
