Together with separate resistors, the air cooled motor starters start three-phase motors with slip-ring rotors of up to 2000 kW and rotor voltages of up to 2000 V. The type and design of the motor starters can be optimally adjusted to the individual application. 3PK4 motor starters compy with the specifications for low-voltage equipment DIN EN 60947-3:2012-12 ; VDE 0660-107;2012-12, IEC 60947-3:2008 +A1:2012, E? 60947-3:2009 + A1:2012, DIN 46 062 DIN EN ISO 12100:2011-03, EN ISO 12100:2010, DIN 46 062 and IEC 292-3. They conform to the EU Low Voltage Directive of 19 February 1973. The Protection class is pursuant to DIN 40 050 : IP54.
