Home / Controls, safety & Regulation / Type 8G:Single pole control thermostat, bulb and capillary, 20A
Type 8G Single pole control thermostat, bulb and capillary
-New temperature ranges,
-Reduced differential,
-Ground terminal,
-Power rating up to 20A 250V,
-Aligned terminals, compatible with 3 way connectors.
Housing dimensions: 43 x 35 x 29 mm (without terminals)
Bulb and capillary: stainless steel, with 150 mm long PVC sleeve on the capillary. Capillary minimum bending radius is 5 mm. No capillary sleeve for temperature ranges above 400°C (750°F)
Temperature sensing element: Oil filled bulb and capillary.
Caution: Temperature ranges above 400°C (750°F) are filled with sodium-potassium eutectic. In case of breakage of the bulb or capillary, this liquid may self-ignite at room temperature in the presence of water or moisture.
Terminals: 6.35 x 0.8 quick connect terminals, 90° bended. Straight terminals or terminals with M4 screws also available on request. (MOQ apply). Terminal positions and alignment allow the use of a connector with flat or bended terminals.
Adjustment: Dia. 6 mm shaft with 4.5 mm flat, length 11.5 mm. Other lengths, screw driver adjustment or fixed setting available on request.
Mounting: Front bracket with 2 x M4 threads, 28 mm distance
Grounding: M4 thread on mounting bracket
Contact: SPDT
Electrical rating, resistive loads:
-Open on temperature rise contact (C-1)
16A 250V, 50 ~60Hz: >100000 cycles,
20A 250V, 50 ~60Hz: ≥ 50000 cycles,
10A 400V, 50 ~60Hz: ≥ 50000 cycles.
-Close on temperature rise contact (C-2): 6A 250V 50 ~60Hz: >100000 cycles
Electrical rating, inductive loads:
-Open on temperature rise contact (C-1): 6A 250V, 50 ~60Hz: >100000 cycles
-Close on temperature rise contact (C-2):0.6A 250V 50 ~60Hz: >100000 cycles
