The 6SL3520-0XK03-0AA0 is the standard-configuration 3 kW member of the G120X wall-mounted family, positioned between the basic -0AB0 and the full-featured -0AF0. It offers a mid-tier I/O complement that covers the majority of pump and fan applications — enough analog and digital channels for a speed reference, run feedback, fault relay, and a room for a secondary sensor — without the cost of the premium variant's maximum I/O count.

How does the -0AA0 compare to the -0AB0 and -0AF0 in practice?

All three share the same 3 kW / 15.4 A power stage, IP65/66 enclosure, C2 EMC filter, and 425 × 240 × 134 mm dimensions. The -0AA0 adds I/O channels beyond the basic set, bridging the gap for applications that need more than start/stop but do not justify the -0AF0. Think of it as the default recommendation for a new design — start with the -0AA0, then move down to -0AB0 if the I/O is overkill or up to -0AF0 if you need the maximum interface count. For the exact terminal-level breakdown, refer to the SINAMICS G120X catalog D 31.

What motor cable length can this drive support?

All G120X variants, including this one, support motor cable runs up to 150 metres without an additional output reactor. The integrated DC link reactor and C2 EMC filter are built into every suffix variant.

Frequently Asked Questions

Is the -0AA0 a good default choice for new infrastructure designs?

Yes. For most new pump and fan applications, the -0AA0 provides a balanced I/O set that covers the typical control scheme — speed reference (analog or fieldbus), run/fault feedback, and a spare digital input for a safety interlock or remote reset. Specifying it as the baseline avoids the risk of under-speccing with the -0AB0 while controlling cost versus the -0AF0.

Does the -0AA0 support the same overload profile as the higher-tier variants?

Yes. All suffix variants share the same power electronics and overload capability: 200% for 3s, 150% for 57s, and 87% for 240s. The suffix only affects I/O and communication configuration.
