Contactor CJX93P30A for heat pump compressor<\/span><\/h2>\n

This CJX93P30A Compressor Contactor is designed for a nominal current of 30A. When voltage is applied to the control coil, the contactor is activated, closing the main contacts. It is important that the control circuit voltage is 230V. This contactor is ideal for starting compressors heat pumps<\/a> with fixed speed. It can also be used to switch high-power peripheral equipment such as circulation pumps, electric heaters and other devices.<\/span><\/p>\n

Nominal characteristics depending on load<\/span><\/h3>\n

The connected load and the supply voltage directly influence the performance of the contactor. The rated current of 30A, mentioned in the name Contactor CJX93P32\u0410, is intended for standard use \u2013 control of three-phase 380V electric motors, category AC-3<\/strong><\/a>.<\/span><\/p>\n

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

CJX93P30A contactor for compressors is designed for a nominal load of 15 kW. For simpler applications, such as light bulbs or electric resistors, the category is recommended. AC-1<\/strong><\/a>For controlling motors with high inertia or reversing, the category is preferred. AC-4<\/strong><\/a>.<\/span><\/p>\n

Construction of contacts and magnetic core<\/span><\/h3>\n

CJX93P30A compressor contactor uses a double-break scheme with a central spring mechanism for high reliability. The magnetic core plates are fixed at 12 points, 6 of which are reinforced with rivets for durability. Rubber dampers reduce vibration, and short-circuiting coils prevent armature recoil at phase zero crossing.<\/span><\/p>\n

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

In circuits with low currents and voltages, oxidation of the contacts can make switching difficult. Auxiliary contacts NC1<\/strong> are equipped with a self-cleaning system: the spring-loaded moving part moves and mechanically cleans the contact surface. Perpendicular grooves increase the efficiency of this process.<\/span><\/p>\n

CJX9 contactor series<\/span><\/h3>\n

The CJX9 series is recognized for its reliable design and versatility in industrial use. The contactors are suitable for switching electrical circuits in various industrial equipment. The CJX93P30A compressor contactor can be combined with thermal relays to protect electrical equipment against overloads. The series covers rated currents from 9A to 95A and offers additional options:<\/span><\/p>\n
