FAQ
1. What is the main function of the Allen-Bradley 1336-SN-SP15A?
The 1336-SN-SP15A is an inverter snubber PCB used as a protective component in compatible Allen-Bradley 1336 drive systems. Its primary function is to help suppress and manage electrical transients generated during inverter switching. By controlling voltage spikes and high-frequency switching disturbances, the snubber circuit helps reduce electrical stress on associated inverter components and supports reliable operation of the drive power section.
2. Which Allen-Bradley drive is the 1336-SN-SP15A designed for?
The 1336-SN-SP15A is specified for use with the Allen-Bradley 1336STEF drive configuration. It is associated with 575 V AC high-power drive applications. Because snubber components are matched to specific power structures and electrical configurations, the exact drive model and hardware configuration should be verified before installation rather than assuming that every 1336 Series drive can use this PCB.
3. What voltage rating is associated with the 1336-SN-SP15A?
The 1336-SN-SP15A is specified for 575 V AC applications. This voltage rating is particularly important because the snubber is directly associated with the power switching section of the inverter. Installing a component with an unsuitable voltage rating can compromise the protection circuit and may expose the inverter power components to excessive transient voltage. The drive’s complete electrical configuration should therefore be checked before replacing the snubber PCB.
4. How many 1336-SN-SP15A snubber boards are required for one drive?
The specified configuration requires three 1336-SN-SP15A snubber PCBs per drive. This is an important consideration when planning spare parts because replacing only one board may not provide a complete set for a drive that uses three units. During maintenance, the condition of all installed snubber boards should be evaluated, especially if one board has failed because the remaining boards may have experienced the same electrical stress.
5. What drive power range is associated with the 1336-SN-SP15A?
The 1336-SN-SP15A is associated with high-power 1336 drive applications in the approximately 300–800 HP range. These systems operate at substantially higher power levels than small industrial AC drives, so the snubber circuit plays an important role in managing switching transients within the inverter power structure. When selecting a replacement, the drive voltage, horsepower range, hardware configuration, and exact spare-part number should all be checked.
6. What symptoms may indicate a problem with the 1336-SN-SP15A?
A damaged snubber PCB may be associated with abnormal inverter operation, increased electrical stress, repeated power-section faults, or visible damage on the snubber components or PCB. In some cases, the drive may experience problems during switching or high-load operation rather than immediately failing at startup. Inspection should include the PCB, associated wiring and terminals, and nearby power components. Because snubber failure can be related to a larger power-section problem, simply replacing the board without checking the cause of the failure may result in another premature failure.
7. What should be checked before replacing a 1336-SN-SP15A?
Before replacement, the drive should be completely de-energized and the appropriate electrical safety procedures should be followed. The exact drive model, voltage rating, power range, and snubber configuration should be confirmed. Technicians should inspect the PCB for burned components, cracked parts, discoloration, loose connections, and signs of overheating. The surrounding inverter power components should also be checked for evidence of short circuits or abnormal switching conditions. Since three snubber boards may be used in one drive, the condition of the complete snubber set should also be considered.
8. Is the Allen-Bradley 1336-SN-SP15A still available as a current product?
The 1336-SN-SP15A is a discontinued Allen-Bradley component. It was identified by Rockwell Automation as a 1336 Series inverter snubber PCB for 575 V, high-power applications, and its official lifecycle status is discontinued. For existing 1336STEF installations, the part can still be relevant as a replacement or maintenance component. When sourcing a replacement, the complete part number and drive configuration should be matched carefully to avoid installing an electrically incompatible snubber board.
