this fixed-temperature limit switch ensures the system remains within safe operating parameters before automatically resetting once temperatures drop by 30 degrees

Safety Interlock: Prevents gas valve energization if the inducer fails to establish a consistent vacuum

Stable Operation: Optimized for 460V inducer motor applications with dual-frequency (50/60 Hz) support for versatile site requirements

Durable Construction: High-grade galvanized steel prevents corrosion and maintains structural integrity in high-humidity environments

Laars Heating Systems E2304800 Limit Switch 318423-701 then align the pen tipThe Laars Heating Systems E2304800 Limit Switch is a mission critical safety component engineered for high temperature protection in hydronic boiler and water heater applications. As a manual reset high limit switch, this device is designed to interrupt the burner circuit when internal temperatures exceed safe operating parameters, specifically calibrated for Laars MightyTherm2 and Pennant series models. For standard boiler configurations, the
