What it is and what it does
The Siemens 6AG1210-1PE21-2UL0 is a SINAMICS G120 Power Module in the FSB frame size, rated for 7.5 kW output. It delivers up to 27 A from a three-phase AC supply, with a full-load efficiency of 0.97. Designed to drive standard induction motors in variable-speed applications, this module requires an associated Control Unit (CU) to operate.
Physical and environmental fit
Mounts in a 292 × 100 × 165 mm envelope (H × W × D) with IP20 protection, so it belongs in a closed panel. Internal air cooling pushes 0.0092 m³/s through the heatsink; keep clearance around the module for airflow. Ambient operating range is -20 to 55 °C, and it will tolerate storage from -25 to 55 °C. For transport, the part can handle -40 to 70 °C.
Protection and braking built in
The module includes overload, short-circuit, ground-fault, overvoltage, and undervoltage protection as standard. For stopping heavy or vertical loads, it supports DC braking, compound braking, and resistance braking with an integrated brake chopper (optional on the larger FSGX frame, but the FSB chopper is internal). Stall and blocked-rotor protection are also present, and parameter locking prevents unauthorized changes.
