A03
A03 MODEL – CUT-IN THERMOSTAT
The A03 type is a constant cut-In thermostat with variable differential, therefore the differential between cut-in and cut-out temperature is variable over the whole range. The minimum differential that can be obtained is 3°C. Calibration is carried out at a barometric pressure of 740 mmHg.
APPLICATIONS
The A03 type Is used to control the evaporation temperature in:
– two door refrigerators
– no-frost refrigerators
CONSTRUCTIONAL FEATURES
A03 type thermostats are compact, robust, and small in size. All their components are made in conformance to Directive 2002/95/CE R0HS, and in particular they have no Cr VI, while the gas used is CFC FREE in compliance with environmental standards.
ELECTRICAL CHARACTERISTICS AND TERMINALS
The terminals are disconnectable tabs with three standard sizes:
2.8 x 0.5mm, 6.3 x 0.8mm and 4.8 x 0.8mm
A03 thermostats have 2 terminals for earth connections:
6.3 x 0.8mm and 4.8 x 0.8mm fastons
3-4 Terminals: 6(6)A250V~µ
CAPILLARY TUBE
The capillary tubes are made of copper with 3µ tin finishing. They can be supplied covered with a white extruded sleeve.
Standard length: 300mm with steps of 50mm up to 3000mm. Upon request we can supply capillary ends with bulbs or curl.
To ensure correct position, it must be in contact with the coldest part of the appliance. There must be a good physical contact between the evaporator and at least the last 120mm of the capillary, it is advisable to position this part of the capillary pointing slightly downwards. If there is insufficient space, the end of the capillary can be bent around the evaporator respecting the minimum bending radius.
