The 6SL3230-3YE54-1AF0 is a 250 kW SINAMICS G120X with C2 EMC compliance and 3C3 coated boards, ordered without operator panel. Electrically identical to the 1AB0 — only the box contents differ.

C2 EMC for commercial buildings — what does it mean in practice?

C2 (EN 61800-3) allows this 250 kW drive to operate on a supply network shared with general-purpose outlets — no dedicated industrial transformer needed. This is the typical requirement for chiller and cooling tower drives in hospitals, airports, and commercial high-rises. The drive must be installed and commissioned by a qualified professional, but it does not require the isolated supply that a C3-classified drive demands. The 3C3 coating adds corrosion protection for the humidity and chemical exposure in mechanical plant rooms.
