The Siemens 6SL3520-0XC00-3AF0 is the absolute lowest-power PROFINET variant in the 0XC connector family of the SINAMICS G115D wall-mounted distributed drive platform — 0.37 kW (0.5 hp) in the compact FSA frame (380 × 156 × 129 mm). With 1.3 A rated output (High Overload), 380–480 V 3-phase supply, C-type connector, and integrated PROFIsafe SIL 2 safety, it is the entry point for C-connector PROFINET: from here, the same C-type cable ecosystem scales to 4 kW in FSB via 0XC02/03/04.

Why the smallest C-connector with PROFINET?

At 0.37 kW, this drive serves the very lightest conveyor functions — singulation gates, mini diverter wheels, reject stations. Integrating these into PROFINET alongside larger C-connector drives creates a unified network where every section — from 0.37 kW to 4 kW — uses the same C-type cable sets and the same TIA Portal engineering environment. The integrated 2-port switch supports daisy-chain topology. PROFIsafe travels on the same bus cable. One connector part number for the entire line, from the smallest gate to the largest pallet conveyor.

What motor types are supported?

The drive delivers 1.3 A rated output current with 200% overload — 2.6 A for 3 seconds. Supports IE3 asynchronous motors, IE4 synchronous reluctance motors, and SIMOGEAR geared motor combinations up to 0.37 kW. Control modes: V/f (0–550 Hz), V/f with FCC, sensorless vector control (0–240 Hz). Integrated 180 V DC brake control. FSA frame: natural convection cooling, IP66 / UL Type 4X.

Frequently Asked Questions

Is 0.37 kW sufficient for industrial duty?

Yes — for the right application. A 0.37 kW motor can drive a singulation gate, a small diverter wheel, or a reject pusher handling lightweight packages. If the section starts under load or handles variable weights, the 0.55 kW (1.7 A) variant provides additional headroom in the same FSA footprint and same C-connector ecosystem.

Is an external braking resistor required?

At 0.37 kW, the integrated 180 V DC brake chopper is more than sufficient. An external braking resistor is not required for any typical application at this power level.
