Contactor CJX93P30A for heat pump compressor

Contactor CJX93P30A for heat pump compressor

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 with fixed speed. It can also be used to switch high-power peripheral equipment such as circulation pumps, electric heaters and other devices.

CJX93P30A Compressor Contactor – Characteristics Conversion Table

Nominal characteristics depending on load

The connected load and the supply voltage directly influence the performance of the contactor. The rated current of 30A, mentioned in the name Contactor CJX93P32А, is intended for standard use – control of three-phase 380V electric motors, category AC-3.

Usage categories

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-1For controlling motors with high inertia or reversing, the category is preferred. AC-4.

Construction of contacts and magnetic core

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.

Auxiliary contacts NC1

In circuits with low currents and voltages, oxidation of the contacts can make switching difficult. Auxiliary contacts NC1 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.
