Overload Relays
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.
