Current-Limiting Performance: Restricts the total energy flow during a fault to protect sensitive downstream components

you must use the ZDB-AF or corresponding series-specific rotation limiters to ensure proper fitment and mechanical strength

Key Benefits for HVAC Technicians:

outlet pressure range

This 24" snap-fit thermocouple is a versatile "truck stock" essential

Utica-Dunkirk 14660001 Spill Switch Current-Limiting Performance: Restricts the totalThe Utica Dunkirk 14660001 Spill Switch is a critical vent safety switch engineered specifically for Dunkirk PWXL boilers and compatible Utica gas fired steam boilers. As a primary safety control, this thermal sensing component monitors the draft hood for abnormal flue gas spillage resulting from chimney obstructions or downdrafts. Calibrated to a 340F activation temperature, the switch breaks the electrical circuit to the gas valve when excessive
