Characteristics These tripping characteristics are mean values of the spread at 20 °C ambient temperature in a cold state. Tripping time depends on response current. On devices at operating temperature the tripping time of the overload relay drops to approx. 25 % of the read value. Speciﬁc characteristics for each individual setting range can be found in the manual. 06/18/2021 Eaton 278459 ED2021 V80.
