With temperatures which deviate from the reference temperature, a slight change of the overload protection properties occurs. In order to determine the
release time using the tripping characteristics the temperature compensation coefficient in accordance with the table must be considered.
Example: An LZM1-A100 is calibrated for a reference temperature of 40 °C.
What happens when it is operated at an ambient temperature of 60 °C ?
At 60 °C, the temperature compensation coefficient of 0.86 results in a reduced operating current of Ir = 100 A × 0.86 = 86 A. In other words
at an ambient temperature of 60 °C the LZM1-A100 trips as if it were set to 86 A.
