The reset snap switch provides an immediate pressure release to protect boiler systems from over‑pressure conditions, helping maintain safe operation and extend equipment life. This **110300** unit is the **Model 5** replacement designed for McDonnell & Miller boilers.
When system pressure exceeds the preset limit, the internal spring‑loaded mechanism trips, opening the circuit and venting excess pressure. After the fault clears, the switch can be manually reset, restoring normal function.
Key System Performance Baselines:
- Pressure Rating: Rated for up to 250 psi, matching original specifications.
- Reset Action: Manual snap‑back reset ensures quick restoration after a trip.
- Compatibility: Direct drop‑in replacement for Model 5 boiler control panels.
- Electrical Rating: 120 V AC, 5 A coil for reliable actuation.
🚨 Application Profile: Ideal for commercial and industrial boiler systems, including hot‑water heating, steam generation, and process heating units where over‑pressure protection is required.
