The Fenwal 18000-504 Thermoswitch Temperature Switch is a temperature-sensitive electrical switch that automatically changes its contact state in response to temperature. Identified by the 18000-504 part number, it belongs to Fenwal's line of thermoswitches used to provide temperature-based control in electrical systems. It is designed for simple, reliable temperature-triggered switching in compatible equipment, serving as a practical solution for thermal protection or process control where a defined temperature threshold governs operation.
