i max as a function of voltage. current deviation as a function of the ambient temperature. ccb701 0 40 50 70 100 120 150 200 100 150 80 i max (%) v rated (%) i max as stated in the electrical data and ordering information tables, is the maximum overload current that may flow through the ptc when passing from the low ohmic to high ohmic state at rated voltage. when other voltages are present after tripping, the i max value can be derived from the above i max as a function of voltage graph. voltages below v rated will allow higher overload currents to pass the ptc. example what maximum overload current is allowed for a thermistor type 2322 662 52513 at 0 c and a maximum voltage after tripping of 180 v rms : i max at 230 v and 25 c = 1.5 a rms : see electrical data and ordering information for 2322 66. 4/5/6...3; max. voltage = 265 v (ac or dc) table. i max at 180 v and 25 c = 1.85 a rms (180 v rms = 78% of 230 v rms gives 123% of i max ). at 0 c this gives 1.68 a rms maximum overload current. see current deviation as a function of the ambient temperature drawing.

typical trip-time as a function of trip current ratio for 145 and 265 volt types. curve 1: typical ? d = 20.0 mm. curve 2: typical ? d = 16.0 mm. curve 3: typical ? d = 12.0 mm. curve 4: typical ? d = 10.0 mm. curve 5: typical ? d = 8.0 mm. curve 6: typical ? d = 6.5 mm. curve 7: typical ? d = 4.5 mm. measured in accordance with ?ec 60738 . for an example, see ?trip-time or switching time (t s )?. trip-time or switching time (t s ) to check the trip-time for a specific ptc, refer to the electrical data and ordering information tables for the value i nt . divide the overload or trip current by this i nt and you realize the factor i t /i nt . this rule is valid for any ambient temperature between 0 and 70 c. adapt the correct non-trip current with the appropriate curve in the current deviation as a function of the ambient temperature graph. the relationship between the i t /i nt factor and the switching time is a function of the ptc diameter; see the above graphs. example what will be the trip-time at i ol = 3 a and t amb = 0 c of a thermistor type 2322 661 54711; 2.5 ? ; ? d = 8.0 mm: i nt from table 1: 470 ma at 25 c i nt : 470 1.12 = 526 ma (0 c). overload current = 3 a; factor i t /i nt : 3 0.526 = 5.70. in the typical trip-time as a function of trip current ratio for 30 to 60 volt types graph , at the 8.0 mm line and i t /i nt = 5.70, the typical trip-time is 1.7 s.
