Semiconductor soft starter 3RW3 8.3.3 Overview tables: compensation factors The following tables list the compensation factors for the circuit-breaker cur- rent setting, the unit rated current and the switching frequency. The values indicate the difference between use with a fan (accessory) and use without a fan. All compensation values apply throughout the complete temperature range, i.e. for 40°, 50° and 60° C. The individual tables successively specify the values forr:
