<p>A starter and thermal protector combination in a hermetic motor- compressor unit comprises a PTC starter (10) and an element (12) for protection against temperature and current overload, the starter (10) and thermal protector (12) being disposed externally of and in proximity to the motor- compressor unit, and a sensor of the protector (12) being substantially in contact with the outer surface of the container (20) of the motor-compressor unit. The operational and constructional characteristics and rating parameters of the starter and protector are chosen in a suitable manner for the correct operation of the combination under all conditions, especially irregular conditions resulting from overloading of any kind. <IMAGE></p> |
