1. Determine the normal operating current:
______ amps
2. Determine the maximum circuit voltage
(Vmax): ______ volts
3. Determine the fault current (Imax):
______ amps
4. Determine the operating temperature range:
Minimum Temperature: ______ C
Maximum Temperature: ______ C
5. Select a product family so that the maximum
rating for Vmax and Imax is higher than the maximum
circuit voltage and fault current in the application.
6. Using the Ihold vs. Temperature Table on the product
family data sheet, select the polymeric device at the
maximum operating temperature with an Ihold greater
than or equal to the normal operating current.
7. Verify that the selected device will trip under fault
conditions by checking in the Itrip table that the fault
current is greater than Itrip for the selected device, at
the lowest operating temperature.
8. Order samples and test in application.
PRODUCT SELECTION
To select the correct polymeric circuit
protection device, complete the information listed below
for the application, and then refer to the resettable
overcurrent protector data sheets.
