Sensing element: Liquid expansion bulb and capillary. The bulb and the capillary go out by the bottom of the enclosure to fit in the heater pocket.
Pilot lights: One pilot light visualizes the thermostat contact output position. The other visualizes the power supply input. Phase and neutral electrical line supply are mandatory for these pilot lights.
Set point adjustment values: 80±8°C (176±15°F), 90±8°C (194±15°F), 110±8°C (230±15°F). Other values can be set between 30°C and 110°C (85°F and 230°F)
Cable input and output: Two M20 cable glands, built-in black PA66.One of them is closed.
Electrical connections: Inside, on screw terminal connection block. It is possible to connect 2 wires 1.5mm² on each terminal.
Earthing: Internal screw terminal and wire with round hole terminal for the immersion heater.
Mounting: By the immersion heater thread or by 2 legs with holes for screws dia. 4 to 5 mm, 114 mm distance.
Identification: Identification label on backside. Set point calibration is printed in °C and °F beside the manual reset button.
Contact: Single pole, open on rise (SPNC)
Electrical rating: 16A res. 250/400VAC
-Electrical life >6.000 cycles.
Minimum storage temperature: -35°C (-30°F)
Maximum ambient temperature: 60°C (140°F)

Elevated terminal plastic connection blocks
In electrothermal connection applications, especially in immersion heater connection boxes appear specific constraints: high ambient temperature, frequent thermal cycles, and confined space around the ends of the heating elements and their terminals, making difficult to the user to make connections. These terminals have been developed to address these constraints.

Main properties of plastic raw materials used for enclosures
The classic housings, with only 5 sides and a lid, require a long and costly layout, most of the time ignoring the application needs: security, fire resistance, water penetration, shocks, UV, temperature, etc. -
Electrical protection classes
The housings are designed to protect electrical equipment located inside. This protection must be considered in the electrical and environmental angles.) -
Thermostats installation
The proper functioning of a thermostat depends primarily on the correct choice of the component, but also the conditions of its installation. Conditions used to calibrate regulating and control equipment in the factory are always ideal laboratory conditions, ensuring measurement accuracy and repeatability. These conditions are rarely those found in practice when installing thermostats. However, with a minimum of constraints, it is possible to optimize assemblies. -
