The Siemens 6SL3520-0XB45-5AB0 is the standard I/O variant in the 0XB connector system of the SINAMICS G115D wall-mounted distributed drive family, rated at 5.5 kW in the FSC fan-cooled frame (425 × 180 × 169 mm, 7.85 kg). With 13.2 A rated output (High Overload), 380–480 V 3-phase supply, and B-connector, it is the first 0XB AB0 variant — a new B-connector catalog path for standard I/O at the FSC power class, parallel to 1XB05-5AB0.

What is the 0XB connector system?

The 0XB is a B-connector catalog path with the "0X" prefix — the tenth G115D code system. It parallels 1XB (also B-connector, "1X" prefix), 0XH, 0XC, and 0XD. At 5.5 kW FSC, the 0XB45-5AB0 is electrically and mechanically identical to the 1XB05-5AB0 — same 13.2 A rated, same FSC frame, same B-connector, same AB0 terminal standard. The distinction is commercial catalog organization. For procurement, 0XB and 1XB are interchangeable at the same power and comm variant.

What motor types are supported?

The drive delivers 13.2 A rated output current with 200% overload — 26.4 A for 3 seconds. Supports IE3 asynchronous motors, IE4 synchronous reluctance motors, and SIMOGEAR geared motor combinations up to 5.5 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 550 mA.

Frequently Asked Questions

Is an external braking resistor required?

At 5.5 kW, an external braking resistor is recommended for decline conveyors, high-inertia loads, and frequent emergency stops. Consult the SINAMICS G115D operating instructions for specific resistor sizing.
