Maximum Heating Circuit Length / Max. Heating Cable Length
For circuit breakers with a rated capacity of up to 20 A or
circuit breakers with a rated capacity of more than 20 A and max. ambient temperature up to +40°C, the max. heating circuit length
can be taken from the data sheet of the respective heating cable.
For circuit breakers with a rated capacity of ≥ 32 A and an ambient temperature higher than +40°C, the following table can be used
to determine the max. permissible heating circuit length (m) for each heating cable type:
