Become a RIB® Relay Distributor in San Antonio
Electrical, HVAC, and controls wholesalers serving San Antonio contractors can apply to add the RIB® line to their catalog. Applying starts with the Functional Devices distributor application, which covers the product categories a distributor plans to stock (relays, transformers, current sensors, and power supplies) and the counties or metro areas they plan to serve.
For a San Antonio distributor, carrying the line means:
- United States Manufacturing: Functional Devices designs and builds the RIB® line in Indiana and has manufactured in the United States since 1969, which supports domestic lead times and consistent supply.
- 100% Product Testing: Every assembled product is tested before it ships, which holds the field failure rate under 1 in 16,000 and reduces returns for the distributor.
- Full-Line Coverage: Relays, current sensors, power supplies, and transformers span switching, load proving, and control power, so contractors can source multiple job components from one supplier.
- Finished, Labeled Devices: RIB® products ship as finished assemblies, which cuts installation and troubleshooting time on the contractor’s end.
- Sales and Engineering Support: Functional Devices sales and engineering staff support product selection for the distributor’s counter and its contractor customers.
- Recurring Commercial Demand: San Antonio’s institutional, government, and healthcare buyers favor United States–made components and reorder steadily as they maintain and upgrade long-held facilities.
