Description
Carrier HH19ZH195 195°F Auto-Reset Cutout Limit Switch
The Carrier HH19ZH195 is an OEM replacement automatic-reset cutout (CO) limit switch rated at 195°F, designed to protect furnaces and heating systems from dangerous overheating conditions. When supply air temperatures exceed the set point, this limit switch opens the circuit to shut down the burner, preventing heat exchanger damage and ensuring safe system operation. Once temperatures return to a safe range, the automatic reset function restores normal operation without requiring manual intervention.
Key Features
- 195°F cutout (CO) temperature set point
- Automatic (AUTO) reset — restores operation once safe temperatures are reached
- OEM Carrier replacement part — ensures proper fit and reliable performance
- Protects heat exchanger and system components from thermal damage
- Designed for use in Carrier furnaces and compatible heating equipment
- Direct drop-in replacement for simplified installation
Application
This limit switch is a critical safety component in forced-air furnace systems. It monitors air temperature in the supply plenum or heat exchanger area and interrupts the burner circuit if temperatures rise above the 195°F threshold. The auto-reset design makes it ideal for applications where nuisance lockouts must be minimized while still maintaining essential overheat protection.
