The Square D 8922-ETB 18/240 is a Series-A DC injection brake module designed to stop AC motors quickly and reliably without mechanical brake wear. It applies a controlled DC current to the motor windings after AC shutdown to provide rapid braking torque and minimize coil heating. The module is configured for the 18/240 voltage variant and mounts directly onto compatible motor starter assemblies. Its compact design simplifies panel integration and reduces maintenance compared to traditional drum or friction braking systems. Suitable for industrial applications where frequent stopping and high reliability are needed. Ensure the module is paired with a starter and a correctly rated supply for safe and effective operation.
