The Reznor 45602 High Limit Switch Auto Reset L180-60F is a temperature-sensitive, secure control used in HVAC heating systems. It prevents the heat source from operating when the air temperature or heat transfer exceeds the high limit, and it precisely resets when it returns to the 120°F to 180°F range. It is mounted in a heating chamber exchanger and unit furnaces and connected to the burner or electric heat control circuit. In HVAC systems, this switch is used to avoid overheating, when the temperature is high, the circuit is open, and when the temperature drops, it is closed.
