Description
The 51-S-2 Xylem-McDonnell & Miller 51-S W/2 Cutoff Switch 135900 is a safety switch. When water pressure or temperature exceeds critical levels, it instantly cuts off power, acting as an essential preventive measure against damage to the pump. It is possible to control two different circuits at once with this double-pole switch because it has two distinct circuits. It works by using a sensor to keep an eye on the temperature or water pressure. The switch cuts off the pump’s power when the predetermined limitations are surpassed, averting potential overheating, dry running, and other dangerous situations. This safety precaution is necessary for several HVAC applications, such as chilled water systems, hydronic heating systems, and boilers. The cutoff switch guards against expensive equipment damage, possible system outages, and even safety hazards from overheating or leakage by preventing pump malfunctions.
