Lochinvar L100208173 Auto Limit Switch 200F

Product Description

The LOCHINVAR L100208173 is a 200 degrees F automatic limit switch designed for high-temperature cutoff protection in commercial and residential hydronic heating systems. This switch monitors operating temperature and automatically interrupts the control circuit when the set point of 200 degrees F is reached, protecting the appliance from overtemperature conditions. It is typically installed by licensed HVAC technicians and boiler mechanics as part of a safety control circuit in water heaters, boilers, or similar heating equipment.

This auto limit switch is suited for use in hydronic boiler systems and water heating applications where precise high-limit protection is required. The automatic reset function allows the switch to restore circuit continuity once temperatures return to a safe operating range, reducing manual intervention during routine service calls. Equipment using this switch type is commonly found in light commercial and residential settings.

Key Features
