RUE(7) 1/15/99 11:28 AM Page 141 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 circuit’s maximum ambient operating temperature and normal operating current. 3. Compare the RUE device’s maximum operating voltage and maximum interrupt current with the circuit’s to be sure the circuit does not exceed the device ratings. 4. Check the RUE device’s time-to-trip to be sure it will protect the circuit. 5. Verify that the circuit’s ambient operating temperatures are within the RUE device’s operating temperature range. 6. Verify that the RUE device’s dimensions fit the application’s space considerations. 7. Independently evaluate and test the suitability and performance of the RUE device in the application. ® Raychem Circuit Protection Devices TUV Rheinland RUE Devices 141 4 RUE(7) 1/15/99 11:28 AM Page 142 RUE Radial Leaded 1. Define the circuit’s 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 circuit’s 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 circuit’s maximum ambient operating temperature. Look down that column to find the value equal to or greater than the circuit’s normal operating current. Now look to the far left of that row to find the part number for the RUE device that will best accommodate the circuit. 4 The thermal derating curve located on the next page is a normalized representation of the data in the table below.

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 device’s 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 20°C for each PolySwitch RUE device. For example, the chart indicates that the typical 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 device’s time-to-trip is too fast or too slow for the circuit, go back to Step 2 and choose an alternate device.
