66L070-0516

The 66L070-0516 is an electronic temperature limiting switch designed specifically to limit temperature conditions in a wide variety of applications, most notably in industrial and commercial settings. This type of thermostat works by controlling a temperature through monitoring and controlling the power supplied to the system being regulated. It is designed to open or close an electrical circuit when the temperature reaches a predetermined level, commonly referred to as its “setpoint”.

The thermostat is available with a variety of contact ratings: 4, 8, 16 and 32 ampere. The operating range can be adjusted from -20°C to +85°C. The control circuitry and temperature sensing elements are assembled in a robust all-metal housing designed to enable installation in confined areas with or without a separate control box. There is an integrated manual reset button and a range of self-adhesive slots enabling the dial to be positioned in the desired location within the system. The unit is connected to the system via two quick-connect terminals for easy installation.

The thermostat has a dual action mechanical thermostatic switch that prevents false tripping and control errors due to temperature fluctuation. When the internal sensing element senses the setpoint, a spring loaded switch opens or closes an electrical circuit in order to regulate the temperature. The switch is precision calibrated to maintain its setpoint accuracy over its entire temperature range.

The unit has an adjustable differential between cooling and heating setpoints. This means that the temperature difference between the heating and cooling setpoints can be varied in order to achieve an optimal ambient temperature range for the application it is installed in. It also features a manual reset button to reset the “weak point” of the thermostat in the event of an over-temperature condition.

The 66L070-0516 thermostat is designed to be used in harsh and hazardous environments where exposure to high levels of heat, moisture or explosive conditions may be present. Uses include clothing dryers, electric motors, heating and air conditioning systems, ovens, and space heaters. It is also suitable for applications in the food and beverage, automotive and medical industries.

In summary, the 66L070-0516 is a reliable and versatile mechanical thermostat designed to limit temperature conditions in a wide variety of applications. It has adjustable setpoint, differential and manual reset features allowing it to be tailored to the application requirements and also offers superior durability and protection against harsh and hazardous conditions.
