4. determine time-to-trip. time-to-trip is the amount of time it takes for a device to switch to a high-resistance state once a fault current has been applied across the device. identifying the rge devices time-to-trip is important in order to provide the desired protection capabilities. if the device you choose trips too fast, undesired or nuisance tripping will occur. if the device trips too slowly, the components being protected may be damaged before the device switches to a high-resistance state. the chart below shows the typical time-to-trip at 25c for each polyswitch rge device. for example, the chart indicates that the typi- cal time-to-trip for rge500 at 10 a is 10 seconds. on the chart below, find the typical time-to-trip for the rge device you selected. if the rge devices time-to-trip is too fast or too slow for the circuit, go back to step 2 and choose an alternate device. typical time-to-trip at 25c a = rge300 b = rge400 c = rge500 d = rge600 e = rge700 f = rge800 g = rge900 h = RGE1000 i = rge1100 j = rge1200 k = rge1400 132 rge devices raychem circuit protection devices rge radial leaded 1 1000 100 10 1 0 .01 .001 10 fault current (a) time-to-trip (s) 100 abcdefh gjk i 4 rge(7) 1/15/99 11:16 am page 132
5. verify ambient operating conditions. ensure that your applications minimum and maximum ambient temperatures are within the operating temperature range of C40c and 85c. maximum device surface temperature in the tripped state is 125c. 6. verify the rge devices dimensions. using dimensions from the table below, compare the dimensions of the rge device you selected with the applications space considerations. product dimensions (millimeters/ inches ) raychem circuit protection devices rge devices 133 rge radial leaded a b c e f marking d c l c l c l c l new new new new part a b c d e f number max. max. typ. min. max. typ. rge300 7.1 (0.28) 11.0 (0.43) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rge400 8.9 (0.35) 12.8 (0.50) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rge500 10.4 (0.41) 14.3 (0.56) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rge600 10.7 (0.42) 17.1 (0.67) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rge700 11.2 (0.44) 19.7 (0.78) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rge800 12.7 (0.50) 20.9 (0.82) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rge900 14.0 (0.55) 21.7 (0.85) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) RGE1000 16.5 (0.65) 24.1 (0.95) 5.2 (0.20) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rge1100 17.5 (0.69) 26.0 (1.02) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rge1200 17.5 (0.69) 28.0 (1.10) 10.2 (0.40) 7.6 (0.30) 3.6 (0.14) 1.4 (0.06) rge1400 27.9 (1.10) 27.9 (1.10) 10.2 (0.40) 7.6 (0.30) 3.4 (0.13) 1.4 (0.06) lead size rge300Crge1100 ? 0.81 (0.032) 20 awg rge1200Crge1400 ? 1.0 (0.040) 18 awg new new * kinked leads are available for rge300 - rge1400 4 rge300Crge1400* rge(7) 1/15/99 11:16 am page 133
