Description
The Reznor RZ146465 A/R Limit Switch is a temperature safety control component designed to monitor operating heat levels in HVAC systems. Configured with a 135F limit setting and a 30F differential, the automatic reset switch interrupts the electrical circuit during excessive temperature conditions and restores operation once heat returns to the designated range. It is commonly installed in heating equipment where thermal protection is required to support controlled airflow and safe system performance during operation. Within the heating assembly, the limit switch operates as a protective control part that supports temperature regulation.
