TECHNICAL FEATURES

Housing dimensions: dia 45 x 44.3 mm

Capillary: copper, capillary length 250mm or 900 mm, 150 mm long PVC sleeve on capillary. Capillary minimum bending radius 5 mm. For technical reasons, we do not recommend to use capillary length longer than 900 mm.

Bulb: Copper, corkscrew type for temperatures from 60 to 130°C(140 to 266°F),tubular  dia 6 mm from 130°C to 170°C (266 to 338°F).

Temperature sensing element: Liquid-filled thermostatic assembly whose boiling causes tripping of the contact. Therefore, unlike liquid filled systems, these thermostats are sensitive to atmospheric pressure, and their reaction time is slower.

Terminals: 6.35 x 0.8 quick connect terminals Adjustment:  fixed setting

Mounting: Backside legs, 2 M4 screws, holes distance 60 mm

Manual reset: fail safe action, center button

Rating: 3 x 16A 250VAC, 3 x 10A 400VAC, resistive (10000 cycles) 3 x 25A 250VAC, 3 x 16A 400VAC (300 cycles)

Contacts: ST, open on temperature rise (snap action contact)

Max ambient temperature on head: 150°C(302°F)

Technical informations associated to this product

  • 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.

  • 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.

  • 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.
