Description

An RB-122 low water cut-off wired for 120 V. It stops the burner firing if the water level in the boiler drops below a safe point, which prevents dry firing — heating a boiler with too little water in it, which cracks sections and heat exchangers and writes off the boiler. The 120 V version switches in the line-voltage circuit, so check which supply the existing control uses before ordering a replacement.
