The Siemens 6SL3520-0XB43-0AB0 is the standard I/O variant in the 0XB connector system of the SINAMICS G115D wall-mounted distributed drive family, rated at 3 kW in the FSB fanless frame (425 × 180 × 134 mm, 7.12 kg). With 7.7 A rated output (High Overload), 380–480 V 3-phase supply, and B-connector, it is the AB0 variant at the highest fanless 0XB power rating — hardwired control for 3 kW conveyor sections, parallel to the 1XB43-0AB0. Natural convection cooling: no fan, zero drive-generated noise.

What motor types are supported?

The drive delivers 7.7 A rated output current with 200% overload — 15.4 A for 3 seconds. Supports IE3 asynchronous motors, IE4 synchronous reluctance motors, and SIMOGEAR geared motor combinations up to 3 kW. Control modes: V/f (0–550 Hz), V/f with FCC, sensorless vector control (0–240 Hz). Integrated 180 V DC brake control. 24 V DC consumption: approximately 290 mA (fanless).

Frequently Asked Questions

Is an external braking resistor required?

At 3 kW, an external braking resistor (minimum 130 Ω for FSB) is recommended for decline conveyors or high-inertia loads. For horizontal conveyors, the internal brake management is typically sufficient.
