For Operation in the Control Cabinet © Siemens AG 2009 3RW Soft Starters 3RW30 for standard applications EMC interference immunity Electrostatic discharge (ESD) Electromagnetic RF fields Conducted RF interference RF voltages and RF currents on cables Surge EMC interference emission EMC interference field strength Burst Radio interference voltage Radio interference suppression filters Degree of noise suppression A (industrial applications) Not required Degree of noise suppression B (applications for residential areas) Control voltage 230 V AC/DC Not available 1) 24 V AC/DC Not required for 3RW30 1. and 3RW30 2.; required for 3RW30 3. and 3RW30 4.
(see Table) 1) Degree of noise suppression B cannot be obtained through the use of filters as the strength of the electromagnetic field is not attenuated by the filter. 6 1) The radio interference suppression filter is used to remove the conducted interference from the main circuit. The field-related emissions comply with degree of noise suppression B. Filter selection applies under standard conditions: 10 starts per hour, start time 4 s at 300 % I e. 6/11 Siemens LV 1 T · 2009 Standard Parameters Electromagnetic compatibility Acc. to EN 60947-4-2 EN 61000-4-2 ±4 kV contact discharge, ±8 kV air discharge EN 61000-4-3 Frequency range: 80 ... 2000 MHz with 80 % at 1 kHz Degree of severity 3:
