Description

A McDonnell & Miller 47-2 low water cut-off with a #2 switch. It shuts the burner down before the boiler water level falls far enough to cause damage — dry firing cracks sections and heat exchangers and writes off a boiler. The switch designation matters: the electrical arrangement determines what it can control and how it integrates with the burner circuit, so match it to the existing installation as well as the mounting.
