More Information

Overview Manuals Brake Duty Protection Environment Application
  • 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.

Availability: Exact condition, stock, price, and shipping time for 1305-KBA09 are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • 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
Description
1305-KBA09 is an Allen-Bradley dynamic brake assembly for documented 460 V Bulletin 1305 Series B and later drives.

The manufacturer table associates 1305-KBA09 with 5 hp / 4 kW drives and identifies a 3.4 kW peak braking-power capability. The assembly uses drive DC-bus energy and is internally fused.

Use only with the specified drive Series and braking application. Verify deceleration duty, ambient conditions, fuse condition, mounting clearance, and host-drive catalog number before energization.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why is Allen-Bradley 1305-KBA09 restricted to Series B and later drives?
The manufacturer warns that use on a Series A drive can damage or disable the drive. Confirm the drive Series from its nameplate before selection.
Does Allen-Bradley 1305-KBA09 provide braking when the incoming supply fails?
It dissipates energy available on the drive DC bus. It is not a backup-power device and cannot maintain motor control after the drive loses usable bus energy.
Why might a 1305-KBA09 fuse operate repeatedly?
Repeated operation can indicate unsuitable deceleration duty, an incorrect brake assembly, a drive fault, or a braking circuit problem. Find the cause before fitting another fuse.
Can Allen-Bradley 1305-KBA09 be repaired in the field?
The manufacturer identifies the assembly as internally fused and not repairable. A failed assembly should be assessed and replaced as the documented service item.
Does Allen-Bradley 1305-KBA09 need unrestricted airflow?
Yes. Brake heat must be dissipated within the published mounting clearances; crowded mounting can shorten component life or cause thermal problems.
Can Allen-Bradley 1305-KBA09 be used in a corrosive or hazardous atmosphere?
No. The published environmental limits exclude corrosive and hazardous atmospheres unless a separately engineered enclosure and installation solution is approved.
Why is drive deceleration important when specifying Allen-Bradley 1305-KBA09?
Rapid deceleration returns more energy to the DC bus. The machine inertia, cycle rate, and commanded ramp determine whether the documented brake duty is suitable.
