-Equipment requesting a very strong resistance to water ingress. The transparent cover allows to visualize the set point and the 2 pilot lights

These liquid expansion rod manual reset limiter can be installed inside pockets as immersion thermostats in pipelines and containers, and as high limit safety in air ducts, in usual industrial applications and environments. (Not suitable for hazardous areas).

-Sealed temperature set point

Housing: Protection class IP 66 upon EN 60529 (waterproof spray water under high pressure and sea splashes, totally dust tight). Body in black PA66, fiber glass reinforced. The transparent polycarbonate cover can be unscrewed by hand, but it is also possible to use a hook spanner. Mechanical impact resistance : IK10. High UV resistance.

Action: Fail safe manual reset high temperature limit.

Set point calibration value: 80±8°C (176±15°F), 90±8°C (194±15°F), 110±8°C (230±15°F). Other calibration temperature on request, between 30°C and 110°C (85°F and 230°F).

Temperature adjustment: Fixed setting, sealed, no access to user.

Sensing element: Liquid expansion bulb and capillary inside nickel plated brass pocket. Thread ½” BSPT. Tube outside diameter 6mm. Located at the bottom of the housing, 2 screws are used to secure standard pockets. (See the compatible stainless steel and brass pockets range in the accessories section)

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.

Cable input and output: Two M20 cable glands, built-in black PA66.

Electrical connections: Inside, on screw terminal connection block. It is possible to connect 2 wires 1.5mm² on each terminal.

Earthing: Internal screw terminal.

Mounting: By the pocket 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)

Technical informations associated to this product

  • 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.
  • Electrical contacts

    As numerous mechanisms exist, we decided not to distinguish on the basis of constructive technique, but according to their operation speed, which is the key element.
