-Sealed calibration point, not adjustable

Housing: Aluminum, IP65, IK10. Grey RAL7032 epoxy painting. Stainless steel captive cover screws. Captive aluminum lid.

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 inside aluminum bracket in contact with the pipe surface.

The bracket design provides optimized thermal contact with 34 mm (1 “, DN25), 60 mm (2″, DN50) and 90 mm (3”, DN80) outside diameter tubes. For intermediate sizes, we recommend the use of thermal grease

Electrical connections: Inside, on screw terminal connection block

Earthing: Internal and external screw terminal.(Possibility to connect 2 wires 1.5mm² on each terminal)

Pilot light: Allow to visualize thermostat contact output position. Standard for all models with transparent window. Non Standard and on special request only for models with plain aluminum cover

Cable input and output: Two M20 cable glands, Black PA66.

Mounting: The thermostat housing can be fixed on the pipe by worm drive hose clamps (DIN3017) , nylon cable ties (Tie wraps upon EN50146, for applications at permanent temperature lower than 85°C), or specific stainless steel punched band (see accessories at the end of this catalog)

Identification: Metallic identification label, riveted. 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)

  • Electrical protection classes

    The housings are designed to protect electrical equipment located inside. This protection must be considered in the electrical and environmental angles.)
  • Description of temperature controls

    Used as control thermostats or as a safety thermostat with manual reset, these thermostats have a disc made of two different metals laminated together for temperature sensing element. These two metals have different expansion coefficients.
  • JPC Design concept of the Y1 types aluminum enclosures

    Y1 range includes a wide range of thermostats in IP65* metal housing with high mechanical resistance (IK10** except models with external knob), intended for commercial or industrial applications covering ranges from -35 °C to +760 °C.
  • 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.
