A starting and protection device for refrigerator motors having a thermal protection device and a PTC resistor, includes a common casing containing the protector and the PTC resistor. The casing is formed by two separate bodies designed to house the protector and the PTC resistor respectively. The bodies are separate and distanced to prevent the protector from being affected by the heat developed by resistor.
Starting and protection device for refrigerator motors of the type comprising a thermal protection device and a PTC resistor, characterised in that it comprises a common casing (1) containing said protector (6) and said PTC resistor (7), which said casing is formed by two separate bodies (4, 5) designed to house the protector and the PTC resistor respectively, which said bodies are separate and distanced to prevent said protector (6) from being affected by the heat developed by resistor (7), wherein said casing (1) is formed by bodies (4, 5) designed to house the protector (6) and the PTC resistor (7), which are separated by a distance such that when the device is fitted to the compressor, one of bodies (4, 5) is located inside the compressor support bracket (9) and the other is located outside said bracket.

This invention relates to a starting and protection device, in particular for refrigerator compressor motors, of the type comprising a PTC resistor and a protective device, both inserted in a casing fitted with connectors which enable it to be connected to the standardised pins present on compressors, and with connectors which allow the subsequent application of a capacitor.
The device according to the invention is characterised by the particular configuration of the casing, which is designed to keep the protector separate and distanced from the PTC resistor.
In particular, the casing of the device comprises two seatings constituted by projecting box-shaped bodies, designed to house the PTC resistor and the protector respectively, the first of which said bodies is designed to be inserted into the bracket present on the compressor to allow the application of the device to the motor connection pins, while the second body remains outside said bracket when the device is fitted.
This invention will now be described in detail, by way of example but not of limitation, by reference to the annexed figures wherein:
FIG. 1 is a plan view of a device according to the invention, assembled;
FIG. 2 is a front view of the device shown in FIG. 1;
The starting device according to the invention comprises a casing assembly 1, designed to house the various components, which is closed by a lid 2 that snaps onto body 1 where it is secured by teeth 3.
Body 1 is shaped so as to define a pair of box-shaped seatings 4 and 5, which are designed to house a protection device 6, and a PTC resistor with support 7, respectively.
Each of said components is fitted with faston connectors 8, which project from the container when the device is assembled so that power cables can be attached.
