Important note: This thermostat is considered as a product by the standards of equipment for
potentially explosive atmospheres.
Its incorporation into equipment or inside an enclosure does not request the approval of the entire
device by a professional competent certified body.
These models with knob adjustment and front mounting allow incorporation inside most existing “Ex e” junction
boxes in aluminum or polyester and inside a fitting height of 71 mm.
These thermostats are intended to monitor or control temperatures in hazardous areas.
They can be used in zones 1 or 2 with gas, smoke and fog, class IIC, surface temperatureT5 or T6, and for
ambient temperature on housing of -50 to +80°C(T5) , or -50 to +70°C (T6).
This thermostat uses a flameproof micro-switch type II2Gb, Ex
dIIC T5/T6.
Electrical connections at end of the cable must be made inside increased safety «EX-e» enclosure, or explosion
proof enclosure «Ex-d» or outside hazardous area
The thermostat capillary exit must be performed by a cable gland with gasket adapted to the diameter of the
capillary and providing the level of protection required by the standard. Outside housings, electrical cable
and thermostat capillary must be mechanically protected.
Approvals: These thermostats are ATEX and IECEx certified.
Atex: INERIS13ATEX0066-X ; IECEx: INE13.0099-X
Housing: aluminum, 82,2 x 37 x 56,5mm (Dimensions without shaft and knob)
Bulb and capillary: Copper for temperature ranges up to 50°C, stainless steel over 50°C.
Capillary length 1500 mm or 3000 mm. Capillary minimum bending radius 5mm.
Temperature sensing element: oil filled bulb and capillary.
Electrical connection: H05SS-F silicone insulated cable, 3 x 1.5 mm², standard length 3m.
Wire ends with crimped terminals. Other lengths on request.
Ground terminals: Two M4 grounding terminals with saddle are located on the side.
Adjustment: Dia. 6 mm shaft with 4.6 mm flat, length 10 mm.
Other shaft lengths available on request:
-20 mm: the third character of the reference (A) becomes M;
-30 mm: the third character of the reference (A) becomes J.
Mounting: Front bracket with 2 x M4 threads, 28 mm distance
Contacts: SPDT (snap action contact)
Electrical rating: Suitable for power control, remote control of relay coils or PLCs
circuits.
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.
