product presentation

Housing dimensions : 60 × 54 × 48mm (without terminals)
Bulb and capillary : Stainless steel, capillary length 250, 750, or 870mm, full length PVC sleeve on capillary up to 70mm of the bulb. PVC sleeve is transparent on the temperature control diastat and green on fail-safe safety diastat.
The bulb diameter of the safety diastat is usually 1mm smaller than that of the temperature control diastat to allow them to be mounted one behind the other in the same pocket. For the same reason, the capillary of the safety diastat is shorter than that of the temperature control diastat.

Contact us for different dimensions.
Capillary minimum bending radius: 5mm

Temperature sensing element : liquid filled bulb and capillary.

Terminals : 6.35 × 0.8 quick connect terminals. M4 screws also available on request.

Adjustment of temperature control set point:  : Dia. 6mm shaft with 4.6mm flat, shaft length 11.5mm. Other lengths or fixed setting available on request.
The temperature control shaft is available with 180 or 270° mechanical angulation.

Manual reset: Fail-safe, sealed fixed setting, front access reset button. Set point value of manual reset is usually 25°C above the maximum adjustment value of the temperature control set point. Other values are possible, provided that tolerances between both set point don’t allow over crossing.
To know more about standard tolerances on manual reset set point, see 85 thermostat catalogue pages.

Mounting : Front bracket with 2 × M4 threads, 28mm distance

Rating : 25(4) A 250VAC, 20(3.3)A 400VAC.
