Applications

-Remote control in usual industrial applications and environments, not hazardous areas, for use as high limit safety.

– Sealed temperature set point

-Internal reset is convenient for products that must not be frequently reset.

Housing: Aluminum, IP65, IK10. Mounted on a SUS304 stainless steel wall mounting plate which keeps the temperature sensing element away from the wall. 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), 130±8°C (266±15°F), 150±8°C (302±15°F), 175±8°C (347±15°F), 220±11°C (428±20°F), 270±13°C (518±23°F), 300±15°C (572±27°F). Other calibration temperature on request, between 30°C and 320°C (85°F and 610°F)

Temperature adjustment:  Fixed setting, sealed, no access to user.

Sensing element: Liquid expansion bulb and capillary. The capillary is protected by a stainless steel corrugated pipe terminated by a silicone tip. A plastic cap plug provided as standard accessory allows locking the flexible metal conduit inside a pocket. (See pockets in the accessories section)

Electrical connections:  Inside, on screw terminal connection block. Possibility to connect two wires 1.5mm² on each terminal.

Pilot light: Allows to visualize limiter contact output position. Standard for all models with transparent window. Non-standard and on special request only for models with plain aluminum cover. (230V, 2 phase power supply, is mandatory for the pilot light)

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

Earthing: Internal and external screw terminal.

Cable output:  M16 cable gland, PA66, for cables up to 10 mm dia.

Mounting: Wall mounting, by 4 holes for screws dia. 4 to 5 mm, 94 x 92 mm distance.

Identification: Metallic identification label, riveted.  Set point calibration is printed in °C and °F beside the manual reset button.

Contact: Single pole, open on temperature 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)
