AAON P86030 Auto Limit Switch 270-300°F, 7.5″ Insertion

Description

The AAON P86030 is an OEM auto-reset limit switch engineered for use in AAON rooftop and air-handling equipment. Designed to protect heat exchangers and other critical components from damaging overtemperature conditions, this limit switch automatically interrupts the heating circuit when supply-air or heat-exchanger temperatures exceed the safe operating threshold, then resets once temperatures return to a safe level.

Key Features

• Auto-reset operation — restores normal system function once temperatures fall back within range
• 270–300°F trip range for precise overheat protection
• 7.5″ insertion depth for proper sensor placement in duct or heat-exchanger applications
• Direct OEM replacement for AAON rooftop units and air handlers
• Rugged construction built to withstand demanding commercial HVAC environments

Application

This limit switch is a direct OEM replacement part sourced for AAON commercial HVAC systems. It is installed in the airstream or adjacent to the heat exchanger to continuously monitor operating temperatures. Should temperatures rise beyond the rated setpoint, the switch opens the control circuit to shut down the heating source, preventing equipment damage and potential safety hazards. The auto-reset feature eliminates the need for manual intervention once the root cause of the overtemperature condition has been resolved.
