Modine 5H0807460001 Limit Switch
The Modine 5H0807460001 Limit Switch is a critical safety component designed for Modine unit heater parts and various industrial HVAC systems. This 145F manual reset limit switch (M/R) functions as a high-limit safety control, strictly monitoring internal heat exchanger temperatures. Engineered for SPST switch operation, the circuit is designed to open on rise when temperatures reach the fixed 145°F threshold, effectively cutting power to the gas valve or ignition control to prevent equipment damage and ensure safe operation. Unlike automatic reset models, this manual reset configuration requires a technician to physically inspect the unit and clear the fault once the cause of overheating is identified. This OEM Modine replacement part is built with a robust, compact housing to withstand the high-cycle thermal stress typical of commercial unit heater limit control applications, maintaining precise calibration and reliable switching for long-term system protection.
Key Benefits:- Precise Thermal Protection: Features a fixed 145°F trip point to prevent heat exchanger cracking or catastrophic failure.
- Manual Reset Safety: Forced intervention ensures that underlying issues like airflow restrictions or blower failure are addressed before the heater resumes operation.
- OEM Compatibility: Exact Modine 5H0807460001 specifications ensure seamless mounting and electrical integration into existing Modine HVAC systems.
- Durable Construction: Designed with high-quality materials to resist wear in demanding industrial and commercial environments.
- Why does my manual reset limit switch keep tripping? This is often caused by airflow issues such as clogged air filters, a failing blower motor, or restricted ductwork. If the switch trips, verify that the fan is moving sufficient air across the heat exchanger.
- Can I replace a 145F switch with a different temperature rating? No. Using a switch with a higher temperature rating can lead to hazardous overheating, while a lower rating will cause nuisance tripping. Always match the OEM 145°F specification.
- Is the 5H0807460001 compatible with other brands? While primarily used in Modine equipment, this part may cross-reference with certain Reznor or Nordyne models; however, field verification of mounting bracket and terminal orientation is required.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
