Laars Heating Systems 2400-055 Limit Switch
For service technicians maintaining Laars Heating Systems, the Laars 2400-055 Limit Switch is a critical safety component designed for precise thermal regulation. This 245F CO AUTO Limit Switch functions as a high-limit protection device, automatically interrupting the control circuit if internal temperatures reach the 245°F threshold. Engineered for compatibility with commercial boiler models including the Laars HWG and Laars CB series, this "new style" switch includes a dedicated mounting bracket for secure installation. As a genuine HVAC replacement part, it ensures the system adheres to operational safety standards by prevent overheating conditions. The automatic reset capability allows the switch to close the circuit once temperatures return to a safe range, minimizing system downtime while maintaining strict equipment protection. Relying on OEM Laars parts like the 2400-055 ensures exact electrical specifications and mechanical fit, which is vital for the long-term reliability of high-output hydronic systems.
Key Benefits- Precise Thermal Cut-Out: Pre-set to 245°F to provide reliable over-temperature protection for commercial boiler heat exchangers.
- Automatic Reset Function: Eliminates the need for manual intervention by restoring power once the system cools below the set point.
- Direct OEM Fit: Specifically designed for Laars HWG and CB commercial boilers, ensuring seamless integration with existing control loops.
- Simplified Installation: Comes equipped with the required mounting bracket, reducing time spent on-site during component replacement.
Which Laars models are compatible with the 2400-055 limit switch?
This switch is primarily used in Laars HWG and CB series commercial boilers, as well as select Summit (SMB/SMW) and Mark II 9600 models. Always verify the part number against your specific unit’s manual.
Does this switch require a manual reset after a trip?
No, the 2400-055 is a CO AUTO (Cut-Out Automatic) switch, meaning it will automatically reset its contacts once the sensed temperature drops below the fixed 245°F limit.
What is the purpose of the 245°F temperature rating?
The 245°F rating acts as a safety ceiling. It is calibrated to shut down the burner or heating source before the water temperature or heat exchanger reach levels that could cause equipment damage or unsafe operating pressures.
