The 6SL3520-1XD01-1AB0 introduces the 1XD code system — a D-connector SINAMICS G115D distributed drive with the "1X" catalog prefix, parallel to the established 0XD (D-connector with "0X" prefix). Delivering 1.1 kW in the compact FSA frame (380 × 156 × 129 mm, natural convection) with AB0 Standard I/O, it extends the D-connector ecosystem to 1.1 kW. Rated for 3.1 A continuous output (HO) at 380–480 V three-phase with 200% overload for 3 seconds. Compatible with IE2/IE3/IE4 motors across 0–550 Hz, IP65 sealed.

What is 1XD and how does it relate to 0XD?

1XD is the D-connector G115D with the "1X" catalog prefix, while 0XD is the D-connector with the "0X" prefix. Same D-connector mechanical interface (cable entry geometry, termination style), same frame sizes, same electrical specs at equivalent power ratings. The "1" vs "0" prefix is commercial catalog organization — not a hardware difference. This mirrors the established 1XB/0XB relationship for B-connector and 1XC/0XC for C-connector. The D-connector is one of three G115D connector ecosystems (alongside B and C), differing in cable entry orientation and termination style — all three are electrically identical at the same power and communication variant.
