AS A FUNCTION OF VOLTAGE 200 Imax (%) 150 100 80 0 40 50 70 100 120 150 Vrated (%) Imax. 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 Imax. value can be derived from the above Imax. as a function of voltage graph. Voltages below Vrated will allow higher overload currents to pass the PTC. TYPICAL TRIP-TIME AS A FUNCTION OF TRIP CURRENT RATIO 102 Curve 1: O Dmax. = 20.5 mm ts Curve 2: O Dmax. = 16.5 mm Curve 3: O Dmax. = 12.5 mm 10 Curve 4: O Dmax. = 10.5 mm Curve 5: O Dmax. = 8.5 mm 1 10-1 Curve 6: O Dmax. = 7.0 mm (1) (2) (3) (4) (5) (6) (7) 1 2 4 6 8 10 12 14 It/Int Curve 7: O Dmax. = 5.0 mm Measured in accordance with "IEC 60738". 16 Trip-time or switching time (ts) To check the trip-time for a specific PTC, refer to the Electrical Data and Ordering Information tables for the value Int. Divide the overload or trip current by this Int and you realize the factor It/Int. This rule is valid for any ambient temperature between 0 C 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 It/Int factor and the switching time is a function of the PTC diameter; see the above graphs. Example What will be the trip-time at Iol = 3 A and Tamb = 0 C of a thermistor type 2381 661 54711; 2.5 ; O Dmax. = 8.5 mm: Int from the table: 470 mA at 25 C Int: 470 x 1.12 = 526 mA (at 0 C). Overload current = 3 A; factor It/Int: 3/0.526 = 5.70. In the typical trip-time as a function of trip current ratio graph, at the 8.5 mm line and It/Int = 5.70, the typical trip-time is 1.7 s.
