The Allen-Bradley auxiliary contact module, identified by the commercial part number 100-FB20, is a control circuit accessory designed for integration with industrial contactors, motor starters, and relay systems. This auxiliary contact provides additional switching contacts that are mechanically linked to the main device, enabling reliable status signalling, electrical interlocking, and control logic functions in automation applications.
Typical features of this product category include:
- Form factor: Compact front-mount or side-mount auxiliary contact block for standard contactor series (mounting compatibility should be verified with the specific contactor or starter).
- Contact configuration: Often available in normally open (NO), normally closed (NC), or changeover configurations; exact contact arrangement for 100-FB20 is not specified in the listing.
- Electrical ratings: Intended for low-voltage control circuits; specific current and voltage ratings are not provided in the source data and should be confirmed from manufacturer documentation.
- Mechanical life: Designed for high switching cycles typical of auxiliary contact blocks in industrial environments.
- Compliance: Manufactured by Allen-Bradley, a Rockwell Automation brand, and distributed by an authorized B2B channel.
This product is listed under the “Auxiliary Contact” category and is supplied with EAN/GTIN 0662072612804 for easy identification and ordering.
