Tripping Characteristics
These tripping characteristics are the mean values of the spread at 20°C ambient temperature in a cold state.
Tripping time depends on response current. With devices at operating temperature, the tripping time of the overload relay reduces to
approximately 25% of the read off value. Specific characteristics for each individual setting range can be found in MN03402001E.
