Technical features

Applications: Protection against the overheating of the heaters due to an abnormal rise of the liquid temperature due to a flow failure. The mounting of the bulbs can be made inside standard dia. 8.5mm pockets, or in an additional thermowell added on request. The thermostat body can be installed in a protective cover of the heating elements outputs, or remotely in a separate control cabinet. They are resettable after tripping, but prior full audit of the circuit is essential to find the cause of overheating and correct it before restarting.

Housing dimensions: Dia 45 × 44.3mm

Capillary: Copper, capillary length 250mm or 900mm, 150mm long PVC sleeve on capillary. Capillary minimum bending radius 5mm.

For technical reasons, we do not recommend to use capillary length longer than 900mm.

Bulb: Copper, dia. 6mm.

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 × 0.8 quick connect terminals

Adjustment: Fixed setting

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

Manual reset: Fail safe action, center button

Rating: 3 × 16A 250VAC, 3 × 10A 400VAC, resistive (10000 cycles), 3 × 25A 250VAC, 3 × 16A 400VAC (300 cycles)

Contacts: Three poles, open on temperature rise (snap action contact), double break.

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