Thermal Stability: Constructed from high-grade materials to withstand the temperature fluctuations common in intensive hydronic heating applications
Most failures result from thermal degradation at the terminals or moisture corrosion within the connector housing
If the actuator is leaking control air or failing to achieve its full stroke under typical pressure ranges (such as 3-13 psi or 5-10 psi)
maintaining system thermal regulation efficiency without the need for field calibration
This auto reset limit switch operates within a precise thermal range of 140-220°F
Modine 5H0749760007 Limit Switch Thermal Stability: Constructed from high-gradeThe Modine 5H0749760007 Limit Switch is a critical OEM replacement part designed for high limit temperature protection in Modine unit heaters and Hot Dawg series garage heaters. As the authorized successor to part number 5H74976 7, this high limit safety control ensures the system remains within safe operating parameters by interrupting the electrical circuit if the heat exchanger exceeds its factory set thermal threshold. Built for heavy duty
