Description
The Marley Engineered Products 4520-11016-000 Manual Reset Limit is a temperature secure control that is used to check the temperature of electric heating equipment. A temperature-sensitive switching part reacts to high temperatures inside the system and closes the electrical circuit once the preset temperature is hit, disconnecting the power supply to heating elements connected to HVAC systems. The manual reset setting is such that the component has to be physically reset once the temperature has dropped to a protective range before the circuit can be reinstated.
