1) The current range that can be covered corresponds to the actual rated current of the 6RA70 SIMOREG DC MASTER (display parameter r072.02). If the rated current is reduced by parameter P076.01 and/or P067 the resulting lower value is valid. Thus the CCP can then be used for a SIMOREG DC MASTER with a rated current higher than 2000 A according to its rating plate (necessary, for example, to obtain partly longer required overload times), if the actual rated current that has been parameterized does not exceed 2000 A. The possible overload capability with 1.8 times the actual rated current can be additionally utilized in the process.
2) Definition of degree of pollution 2: Under normal conditions, only non-conductive pollution occurs. Occasionally, pollution may become conductive for a short period of time when the electronic equipment is not in operation.
