Aaon R31410 High-Limit Safety Switch 220F Enclosed 3-Inch

The Aaon R31410 is a genuine OEM high-limit safety switch designed for use in Aaon commercial HVAC rooftop units and air handlers. This enclosed-style limit switch features a 220°F trip point and a 3.00-inch sensing element insertion depth, making it a direct replacement for the original factory-installed component.

As a high-limit safety device, the R31410 monitors internal air temperature and automatically interrupts the electrical circuit when temperatures exceed the 220°F threshold, protecting the heat exchanger and surrounding components from thermal damage. The enclosed housing provides durability in demanding commercial HVAC environments.
