At 0.55 kW (1.7 A rated, 3.4 A overload), the 6SL3520-0XA20-5AA0 is part of the 0XA20 series — the 0XA2x catalog system's entry-level FSA sub-series covering 0.37–0.75 kW. The 0XA20-5 fills the middle slot: above the 0.37 kW baseline, below the 0.75 kW workhorse, sharing the identical 380 × 156 × 129 mm FSA envelope and 364.5 × 145 mm mounting pattern with every other FSA drive in the G115D range.

Where does the 0XA20 series fit in the G115D catalog landscape?

The G115D is offered under multiple parallel catalog code systems — 0XA6x, 0XA2x, 1XE, 0XE, 2XE — all referencing the same hardware platform. The 0XA20 sub-series (0XA20-3 = 0.37 kW, 0XA20-5 = 0.55 kW, 0XA20-7 = 0.75 kW) maps to the FSA frame's lower power segment. For the specifying engineer, the choice between 0XA20-5 and its 0XA60-5 or 1XE40-5 counterparts is a commercial decision — regional availability, frame-contract pricing, or preferred distribution channel — not a technical one. The drive itself is the same: 3 AC 380–480 V input, 0–550 Hz output, PROFINET/Ethernet IP, integrated C2 filter, and 37.6 W power loss on natural convection.

Key specifications

The drive operates from a 3 AC 380–480 V supply (45–66 Hz) with an output frequency range of 0–550 Hz. High-overload capability delivers 200% for 3 seconds and 150% for 57 seconds. The 350 Ω integrated braking resistor supports dynamic braking. Integrated PROFINET and Ethernet IP interfaces connect directly to SIMATIC controllers. The built-in C2 RFI filter meets EN 61800-3 Category C2 conducted emission limits.
