The 90-340 switching relay is designed for 100% duty cycles in fan control and general appliance switching
This temperature limit switch provides the reliability field technicians require for reducing callbacks and maintaining peak system efficiency during heavy heating cycles
Durable Construction: Heavy-duty housing designed to withstand the thermal demands of heating and cooling equipment
which is standard for the 2473/M573 actuator series to ensure proper torque and valve seating force
Tripping is typically caused by inadequate airflow
Lochinvar & A.O. Smith 100233264 Bulbwell The 90-340 switching relay isThe Lochinvar 100233264 Bulbwell is a precision engineered immersion well designed for accurate temperature sensing in commercial boilers and water heaters. As a direct OEM replacement part, this component ensures the aquastat sensor or thermostat bulb is properly isolated from the high pressure system fluid while maintaining optimal thermal conductivity. This specific model is functionally identical to Lochinvar TST2301 and TST2301K, providing a
