Description
The Reznor RZ196950 Manual Reset Limit Switch/Thermostat Yellow shuts down electrical operation when equipment temperatures rise beyond the 250F safety limit during active heating cycles. Its thermal sensing mechanism reacts to excessive heat by opening the control circuit and requiring manual reset before operation can resume within HVAC systems such as industrial unit heaters, gas-fired furnaces, and process heating equipment. This thermostat switch is positioned near high-temperature sections where continuous thermal protection is necessary to prevent unsafe operating conditions. Its resettable safety operation limits overheating exposure and protects surrounding components from thermal damage.
