Type 82: 3 pole manual reset high limit, fail safe



Housing dimensions: dia 45 x 44.3 mm

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: Backside legs, 2 M4 screws, holes distance 60 mm

Manual reset:  fail safe action, center button

Rating: 3 x16A 250VAC, 3 x10A 400VAC

Contacts: ST, open on temperature rise (snap action contact)

Max ambient temperature on head: 150°C (302°F)
