Modine 5H0750020003 — 260°F Manual Reset SPST Rollout Switch
The Modine 5H0750020003 is an OEM rollout safety switch engineered to protect heating equipment from the hazards of burner flame rollout. When abnormal combustion causes flames to escape the burner compartment, this switch responds by interrupting the circuit and shutting down the system before damage or injury can occur.
Key Features
- 260°F trip temperature — activates at high-limit threshold to stop unsafe operation
- Manual reset (M/R) design — requires deliberate technician reset after trip, preventing automatic restart until the root cause is identified and corrected
- SPST (Single Pole, Single Throw) configuration — simple, reliable circuit interruption
- Direct OEM replacement for compatible Modine heating equipment
- Durable construction built to withstand the demanding thermal environment of a burner compartment
Why Manual Reset Matters
Unlike automatic-reset limit switches, a manual reset rollout switch demands a service call before the unit can be restarted. This is a critical safety feature — flame rollout is a symptom of a serious underlying problem such as a cracked heat exchanger, blocked flue, or inadequate combustion air. The manual reset design ensures the hazard is diagnosed and resolved before the equipment is returned to service.
Application
- Designed for use in Modine unit heaters and heating equipment
- Mounts in the burner compartment to monitor for flame rollout conditions
- Ideal for commercial and industrial heating applications
