Characteristics of current dependence
The special feature of the 01 and 02 series is that they are temperature-sensitive switches. In their rated operation (rated current), they exhibit very low self-heating due to the current. Therefore, a switching point reduction takes place at most within the nominal switching temperature tolerance.
