TYPICAL TRIP-TIME AS A FUNCTION OF TRIP CURRENT RATIO
Trip-time or switching time (t
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.
