Contactor CJX93P40A for heat pump compressor<\/span><\/h2>\n

This CJX93P40A Compressor Contactor is designed for a rated current of 40A<\/strong>. When voltage is applied to the control coil, the contactor switches, closing the main contacts. It is important to note that the voltage in the control circuit must be 230V. This contactor is suitable for starting compressors heat pumps<\/a> with fixed speed. It can also be used as a switch for high-power peripheral equipment, such as circulation pumps, electric heaters and other equipment.<\/span><\/p>\n

CJX93P40A contactor for compressor. Nominal characteristics depending on load<\/strong><\/span><\/h2>\n

The connected load and the supply voltage directly influence the rated characteristics of the contactor. For example, the rated current 40A<\/strong>, indicated on the housing and in the device name, refers to standard use \u2014 control of electric motors with three-phase 380V power supply in the category AC-3<\/strong>.<\/span><\/p>\n

Task categories<\/span><\/h3>\n

This CJX93P40A Compressor Contactor is designed for a standard load of 18,5 kW<\/strong>For less demanding applications, such as incandescent bulbs or electric resistances (TENs), the most suitable category is AC-1<\/strong><\/a>. On the other hand, if the device controls motors with heavy mechanisms or changes in the direction of rotation, the category is preferable. AC-4<\/strong><\/a>.<\/span><\/p>\n

Contact and magnet construction<\/span><\/h3>\n

Contactor CJX93P40\u0410 uses the classic double-break scheme. In addition, the central moving part is equipped with a spring to increase reliability. Manufacturers have provided for fastening the magnetic plates in 12 places, six of them by hammering, to increase the strength of the structure. To reduce vibrations, rubber dampers have been added to the fixed part, and over-tightened coils prevent the armature from rebounding when the phase crosses zero.<\/span><\/p>\n

Auxiliary contacts NC1<\/span><\/h3>\n

In control circuits, where currents and voltages are low, switching can be difficult due to the oxide film on the contacts. During switching, the spring-loaded moving part moves, cleaning the top layer of the contacts. As a result, the perpendicular markings increase friction and provide even more effective cleaning.<\/span><\/p>\n
