 The indicated electromagnetic tripping values apply to a frequency range of 16 2/3 ... 60 Hz. For different network
frequencies or direct current the values change according to the multiplier in the table below
 The thermal releases are calibrated to a nominal reference ambient temperature; for Z and K, the value is 20 °C, for B and C = 30 °C.
In the case of higher ambient temperatures, the current values fall by ca. 6 % for each 10 K temperature rise.
 As from operating temperature (after I 1 > 1 h or, as applicable, 2 h).

1) The indicated electromagnetic tripping values apply to a frequency range of 16 2/3... 60 Hz. For different network frequencies or direct current the values change
according to the multipler in the table below
2) The thermal releases are calibrated to a nominal reference ambient temperature; for Z and K, the value is 40°C, for B, C and D is 30°C. In the case of higher ambient
temperatures, the current values fall by ca. 6% for each 10 K temperature rise.
3) As from operating temperature (after I > 1h or, as applicable, 2h).
