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 RXE 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 RXE device. For example, the chart indicates that the
typical time-to-trip for RXE050 at 5 A is 0.3 second.
On the chart below, find the typical time-to-trip for the RXE device you
selected. If the RXE device’s time-to-trip is too fast or too slow for the
circuit, go back to Step 2 and choose an alternate device.
