Type 8X: DPNC manual reset high limit, fail safe

TECHNICAL FEATURES

 

Housing dimensions: 43 x 35 x 29 mm (without terminals and diaphragm)

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: Front bushing, with M10x1

Manual reset: fail safe action, front access button

Rating: 20A 250VAC

Contacts: DPST  (snap action contact)

Max ambient temperature on head: 125°C (257°F)
