Limits inrush while the Basic Line Module DC link is precharged.
Product Profile
6SL3000-0KH14-0AA0 is a Siemens SINAMICS S spare-part pre-charging resistor rated at 4.0 ohms for the documented Basic Line Module precharge circuit.
Siemens specifies the resistor for 3 AC 500–690 V service, 47–63 Hz, with a pulse-energy limit of 18,000 Ws and a minimum interval of three minutes between precharge pulses.
The resistor becomes hot during operation. Enclosure ventilation, clearance, conductor sizing and protection must follow the SINAMICS installation manual.

FAQ
Q01Can 6SL3000-0KH14-0AA0 be energized continuously?
No. It is a pulse-duty precharging resistor. The documented 18,000 Ws limit and three-minute interval must be respected.
Q02What information is needed to quote 6SL3000-0KH14-0AA0?
Provide the Basic Line Module MLFB, supply voltage, frame size, resistor arrangement, cabinet photographs and failed-part label.
Q03Why must cooling clearance be reviewed for 6SL3000-0KH14-0AA0?
The resistor becomes hot during precharge; inadequate ventilation or contact with heat-sensitive material can damage the cabinet and wiring.
Q04Can a resistor with the same nominal ohms replace 6SL3000-0KH14-0AA0?
Not by resistance alone. Pulse energy, voltage, insulation, mounting, temperature and Siemens system approval must also match.
Q05What should be tested after replacing 6SL3000-0KH14-0AA0?
Verify resistance, insulation, wiring, contactor sequence, precharge time, DC-link rise, temperature clearance and normal line-module diagnostics.
