Description
The Weil McLain 383-500-643 Low Water Cut-Off Probe 24V is a safety control component used to monitor water levels in boiler systems. It detects low water conditions and sends a signal to shut down or restrict operation when levels fall below the required threshold, helping prevent overheating or damage. Frequently used in residential and commercial heating systems, it supports safe boiler operation by ensuring proper water presence during the heating cycle. This probe is typically installed during maintenance or replacement work to maintain system protection and reliable performance of the overall heating equipment.
