Thermal Cut-Out for Elecro Electric Heater

The thermal cut-out is a key safety element of Elecro electric flow heaters, preventing dangerous overheating in the event of stopped water flow or another operating anomaly. When the set limit temperature is exceeded, the cut-out interrupts the power supply to the heating elements, thereby preventing damage to the heater, the surrounding piping or, in extreme cases, even a fire. It is a single-use or resettable cut-out depending on the design – once the cause of overheating has subsided, it can be easily reset without replacement. The original part guarantees the correct switching temperature parameters corresponding to the specification of Elecro heaters. Regular inspection and possible replacement of the cut-out is part of preventive maintenance of the heating system and a condition for maintaining the manufacturer’s warranty.
