    General rules for installation:
    Important Note: These thermostats are considered to be material by the standards of equipment for potentially explosive atmospheres. They are intended to monitor or control the temperatures in hazardous areas. Thermostat, housing and terminal block are indivisible.
    In gas explosive atmospheres, they can be used in zones 1 or 2 in the presence of gas, smoke and fog, class IIC, surface temperature T6, and ambient temperature on the enclosure from -50 to +60°C, or from -50 to +70°C.
    In dust explosive atmospheres, they can be used in zones 21 and 22
    These thermostats have explosion-proof microswitch type II2Gb, Ex dIIC according to IEC/EN 60079-1, embedded in an increased safety aluminum enclosure according to IEC/EN 60079-7.
    Ex identification :
    Gas explosive atmospheres:

    Dust explosive atmospheres:
    Ex 2D Ex tb IIIC T85°C Db
    Approvals: These products are ATEX and IECEx certified
    Atex: pending; IECEx: pending
    Housing: aluminum, 140 x 110 x 90mm (Dimensions without cable gland), with epoxy painting, RAL7032 (thickness less than 0.2mm)
    Temperature sensing element: oil filled stainless steel rod, liquid expansion principle. Standard rod lengths are 230 and 300mm, but on request, it is possible to make 450mm and 600mm
    Electrical connection: On built-in junction block, 4mm², screw terminals. 7 terminals for neutral, ground and line, including jumpers between input and output for neutral and ground. Large space provided for connection.
    A built in junction block, type Push-In® is available on request.
    Cable glands: two M25 metal cable glands can be used for cable from 9 to 13mm or 13 to 16mm. There is a cable locking saddle inside the enclosure, at each cable gland input.
    Other cable glands for round cable, flat cable or independent conductors are available on request
    Ground terminals: Two M4 grounding terminals with saddle are located on the outside of enclosure. 2 grounding terminals are located on the junction block.
    Adjustment: With knob printed in °C (°F on request). Adjustment is possible only after removing the cover, and when the electrical supply is powered off.
    Mounting: By the 3/8 thread or by the dia. 14.5mm bushing located at the rod end under the enclosure. These devices allow the use of fittings, bracket, flanges, pockets and other accessories described in the last section of this catalogue
    Contacts: SPDT (snap action contact)
    Electrical rating: Suitable for power control, remote control of relay coils or PLCs circuits, and direct power switching.
    These devices use silver contacts or silver alloy contacts. Due to the possible oxidation of the contacts in time, we do not recommend the use of AC or DC low-voltage circuits (24V or less) if the switched intensity is less than 100mA, or the switched power less than 800mW. Contact us for those applications that require gold-plated contacts. The electrical ratings given are normalized resistive circuit values.

    *Reduced differential types are not suitable for 400VAC applications.
    **The filling liquid of these thermostatic assemblies has a freezing temperature below -40 ° C. However it is important to protect the bulb and /or the capillary against the risk of freezing if a temperature below -35 ° C can be reached in operation. Acceptable storage temperature: -50 ° C. For these types, maximum ambient temperature acceptable on enclosure : 60°C.
    *** In these applications, the enclosure surface temperature class T6 may be reduced to T5. It is important that the process temperature is not transmitted to the housing and that it does not exceed its maximum allowable temperature.
