- Dynamic-brake hardware for documented 460 V Bulletin 1305 Series B and later drives
- Internally fused assembly using energy from the host drive DC bus
- Published for 5 hp / 4 kW host-drive applications with defined braking duty
Allen-Bradley 1305-KBA09 is a documented dynamic brake assembly for compatible 460 V Bulletin 1305 Series B and later drives.
It dissipates regenerated motor energy during deceleration through the drive DC bus. Correct selection depends on host-drive Series, machine inertia, deceleration profile, and the actual braking cycle.
Use the official mounting and environmental limits. Inspect the braking circuit and correct the underlying cause before replacing a repeatedly operated fuse or assembly.

- Evaluate machine inertia and commanded deceleration against the published braking-duty limits
- Use the brake only with the documented 460 V, 5 hp / 4 kW host-drive application
- Do not treat dynamic braking as a source of ride-through power after loss of incoming supply
- Verify the specified internal fuse type and rating before returning the drive to service
- Investigate repeated fuse operation instead of replacing fuses without fault analysis
- Confirm all brake-circuit wiring and host-drive compatibility before energization
- Mount vertically with the manufacturer-required free space for heat dissipation
- Use within the published temperature, humidity, and altitude limits
- Do not install where corrosive or hazardous atmospheric exposure is present without approved engineering controls
- Controlled deceleration of compatible 460 V Bulletin 1305 motor-drive applications
- Machines with regenerative energy during programmed motor speed reduction
- Industrial processes requiring documented dynamic-brake energy dissipation
