1)
The thermal releases are calibrated to a nominal reference ambient temperature; for B and C the reference value is 30 °C.
In the case of higher ambient temperatures, the current values fall by approx. 6 % for each 10 K temperature rise.
2)
The indicated tripping values of electromagnetic tripping devices apply to a frequency of 50/60 Hz.
The thermal release operates independent of frequency.

Internal resistances and power loss are subject to application-specific and environment-specific conditions and are therefore to be considered as typical values.
