rue selection guide and product data this section has two parts: ? a selection guide that walks you through the process of selecting the correct rue device for a circuit. ? product data that outlines electrical characteristics, physical characteristics, agency recognitions, environmental specifications, component layouts, tape and reel specifications, and ordering information for rue devices. rue selection guide follow these seven steps to select a polyswitch rue device for a circuit: 1. define the operating parameters for the circuit. these include: ? maximum ambient operating temperature ? normal operating current ? maximum operating voltage (rue is 30 v maximum) ? maximum interrupt current 2. select the rue device that accommodates the circuits maximum ambient operating temperature and normal operating current. 3. compare the rue devices maximum operating voltage and maxi- mum interrupt current with the circuits to be sure the circuit does not exceed the device ratings. 4. check the rue devices time-to-trip to be sure it will protect the circuit. 5. verify that the circuits ambient operating temperatures are within the rue devices operating temperature range. 6. verify that the rue devices dimensions fit the applications space considerations. 7. independently evaluate and test the suitability and performance of the rue device in the application. raychem circuit protection devices rue devices 141 tuv rheinland a 4 rue(7) 1/15/99 11:28 am page 141
1. define the circuits operating parameters. fill in the following information about the circuit: maximum ambient operating temperature _______________ normal operating current _______________ maximum operating voltage (rue is 30 v max.) _______________ maximum interrupt current _______________ 2. select the polyswitch rue device that will accommodate the circuits maximum ambient operating temperature and normal operating current. look across the top of the table below to find the temperature that most closely matches the circuits maximum ambient operating temper- ature. look down that column to find the value equal to or greater than the circuits normal operating current. now look to the far left of that row to find the part number for the rue device that will best accommo- date the circuit. the thermal derating curve located on the next page is a normalized representation of the data in the table below. i hold vs. temperature part maximum ambient operating temperatures (c) number C40 C20 0 20 40 50 60 70 85 rue090 1.31 1.17 1.04 0.90 0.75 0.69 0.61 0.55 0.47 rue110 1.60 1.43 1.27 1.10 0.91 0.85 0.75 0.67 0.57 rue135 1.96 1.76 1.55 1.35 1.12 1.04 0.92 0.82 0.70 rue160 2.32 2.08 1.84 1.60 1.33 1.23 1.09 0.98 0.83 rue185 2.68 2.41 2.13 1.85 1.54 1.42 1.26 1.13 0.96 rue250 3.63 3.25 2.88 2.50 2.08 1.93 1.70 1.53 1.30 rue300 4.35 3.90 3.45 3.00 2.49 2.31 2.04 1.83 1.56 rue400 5.80 5.20 4.60 4.00 3.32 3.08 2.72 2.44 2.08 rue500 7.25 6.50 5.75 5.00 4.15 3.85 3.40 3.05 2.60 rue600 8.70 7.80 6.90 6.00 4.98 4.62 4.08 3.66 3.12 rue700 10.15 9.10 8.05 7.00 5.81 5.39 4.76 4.27 3.64 rue800 11.60 10.40 9.20 8.00 6.64 6.16 5.44 4.88 4.16 rue900 13.05 11.70 10.35 9.00 7.47 6.93 6.12 5.49 4.68 142 rue devices raychem circuit protection devices rue radial leaded 4 rue(7) 1/15/99 11:28 am page 142

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 rue 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 20c for each polyswitch rue device. for example, the chart indicates that the typi- cal time-to-trip for rue110 at 8 a is 1 second. on the chart below, find the typical time-to-trip for the rue device you selected. if the rue 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 20c a = rue090 b = rue110 c = rue135 d = rue160 e = rue185 f = rue250 g = rue300 h = rue400 i = rue500 j = rue600 k = rue700 l = rue800 m = rue900 144 rue devices raychem circuit protection devices rue radial leaded 1000 1 10 100 fault current (a) time-to-trip (s) m l k j i h g f e d c b a 100 10 1 0.1 0.01 0.001 4 rue(7) 1/15/99 11:28 am page 144
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 rue devices dimensions. using dimensions from the table below, compare the dimensions of the rue device you selected with the applications space considerations. product dimensions (millimeters/ inches ) part a b c d e f number max. max. typ. min. max. typ. rue090 7.4 (0.29) 12.2 (0.48) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 0.8 (0.03) rue110 7.4 (0.29) 14.2 (0.56) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 0.8 (0.03) rue135 8.9 (0.35) 13.5 (0.53) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 0.8 (0.03) rue160 8.9 (0.35) 15.2 (0.60) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 0.8 (0.03) rue185 10.2 (0.40) 15.7 (0.62) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 0.8 (0.03) rue250 11.4 (0.45) 18.3 (0.72) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 0.8 (0.03) rue300 11.4 (0.45) 17.3 (0.68) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rue400 14.0 (0.55) 20.1 (0.79) 5.1 (0.20) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rue500 14.0 (0.55) 24.9 (0.98) 10.2 (0.40) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rue600 16.5 (0.65) 24.9 (0.98) 10.2 (0.40) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rue700 19.1 (0.75) 26.7 (1.05) 10.2 (0.40) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rue800 21.6 (0.85) 29.2 (1.15) 10.2 (0.40) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) rue900 24.1 (0.95) 29.7 (1.17) 10.2 (0.40) 7.6 (0.30) 3.0 (0.12) 1.2 (0.05) raychem circuit protection devices rue devices 145 lead size rue090Crue250 ? 0.51 (0.020) 24 awg rue300Crue900 ? 0.81 ( 0.032) 20 awg rue090Crue250* rue300Crue900** a b marking c f e d c l c l c l c l a b c e f marking d c l c l c l c l rue radial leaded * straight leads are available ** kinked leads are available 4 rue(7) 1/15/99 11:28 am page 145
