Modine 5H0750020005 M/R Limit Switch 240°F

The Modine 5H0750020005 M/R Limit Switch is a thermal safety switching element used to monitor excessive temperature levels inside heating equipment assemblies. It is rated to react at a 240F threshold, opening the circuit when internal heat rises beyond the set point and resetting once conditions return to normal operating range depending on system. In HVAC systems it is typically used in heating units and similar gas-fired equipment, where it is placed on or near the heat exchanger section to track temperature buildup.
