Frequently Asked Questions about 100-FA11
Question: What is the Allen-Bradley 100-FA11 used for?
Date Update:16/06/2025
Answer:

The Allen-Bradley 100-FA11 is a front-mounted auxiliary contact block designed for use with Allen-Bradley 100-C series contactors. It provides an additional pair of contacts—1 normally open (NO) and 1 normally closed (NC)—to expand the functionality of the contactor. These auxiliary contacts allow for control logic functions such as signaling, interlocking, or feedback in motor starters and control systems. The 100-FA11 snaps onto the front of 100-C09 to 100-C97 contactors without tools, making it easy to install. This accessory is ideal for systems that require additional contact points for safe and efficient control.

Question: Which contactors are compatible with this auxiliary block?
Date Update:16/06/2025
Answer:

This accessory is compatible with a specific range of Allen-Bradley contactors:

  • Fits all 100-C series contactors from 100-C09 to 100-C97.
  • Mounts directly on the front of the contactor.
  • No adapters or modifications are needed.
  • Only one unit can be installed per contactor front.

This ensures seamless mechanical and electrical integration within the control system.

Question: How many auxiliaries can I add to a single contactor?
Date Update:16/06/2025
Answer:

Auxiliary contact blocks can be added in a modular fashion:

  • Only one 100-FA11 can be mounted to the front of the contactor.
  • Additional poles can be added via side-mounted accessories.
  • Up to six auxiliary poles can be added when combining front and side mounts.
  • Check system requirements and contactor limitations before adding.

This provides flexible options for expanding control functionality as needed.

Question: What are the alternatives if I need a different contact configuration?
Date Update:16/06/2025
Answer:

Allen-Bradley offers several front-mounted auxiliary contact blocks for various configurations:

  • 100-FA20: Two normally open (2NO) contacts.
  • 100-FA02: Two normally closed (2NC) contacts.
  • 100-FA11: One NO and one NC contact (this model).

Each model snaps onto the same contactors and has the same terminal style. Select the version that aligns with your circuit logic needs.

Question: Is the 100-FA11 still in production?
Date Update:16/06/2025
Answer:

Yes, the Allen-Bradley 100-FA11 is currently in production and listed as an active product. It is widely supported in Rockwell Automation’s catalog and remains a key accessory for 100-C series contactors.
