FJ series global minimum class AC contactor and thermal overload relay

Design of high-efficiency magnetic system based on three-dimensional electromagnetic field analysis. The same external dimensions of AC electromagnet and DC electromagnet are realized. (FJ-B06, B09, B12) Development of DC magnetic system ● The magnetic system with small size and low energy consumption has been developed by using permanent magnets. ● Strive to minimize the leakage magnetic flux, reduce the loss and realize miniaturization by optimizing the magnetic circuit. The direct drive power of the electromagnetic system is only 2.4W, which can realize the direct drive of the PLC output signal. Development of AC magnetic system ● Optimization of iron core structure. ● The iron core fixed rivet is arranged at the best position that will not affect the magnetic circuit, which can reduce the eddy current loss caused by it. Using the above optimal design, the coil electromagnetic system has been developed with a power consumption of 4.5VA, which meets the level 2 standard of energy efficiency, and belongs to energy-saving products. The optimization of thermal elements and reversing mechanism is realized through 3D thermal imaging analysis and simulation test of reversing mechanism. 3D thermal imaging analysis The discussion of thermal elements is carried out through 3D thermal imaging analysis. The high efficiency of heating and the stable bending of bimetallic sheet further realize the miniaturization of the product.

Product Details

Design of high-efficiency magnetic system based on three-dimensional electromagnetic field analysis. The same external dimensions of AC electromagnet and DC electromagnet are realized. (FJ-B06, B09, B12)
Development of DC magnetic system
● The magnetic system with small size and low energy consumption has been developed by using permanent magnets.
● Strive to minimize the leakage magnetic flux, reduce the loss and realize miniaturization by optimizing the magnetic circuit. The direct drive power of the electromagnetic system is only 2.4W, which can realize the direct drive of the PLC output signal.
Development of AC magnetic system
● Optimization of iron core structure.
● The iron core fixed rivet is arranged at the best position that will not affect the magnetic circuit, which can reduce the eddy current loss caused by it.
Using the above optimal design, the coil electromagnetic system has been developed with a power consumption of 4.5VA, which meets the level 2 standard of energy efficiency, and belongs to energy-saving products.
The optimization of thermal elements and reversing mechanism is realized through 3D thermal imaging analysis and simulation test of reversing mechanism.
3D thermal imaging analysis
The discussion of thermal elements is carried out through 3D thermal imaging analysis. The high efficiency of heating and the stable bending of bimetallic sheet further realize the miniaturization of the product.
Simulation of reverse mechanism
Through the simulation test of the reverse mechanism, the miniaturization of the reverse mechanism is realized, and the stable action characteristics are obtained, killing two birds with one stone.
Security
Electric AC contactor with mirror contact
The mirror contact in Annex F of IEC 60947-4-1 can be used in the combination of single AC contactor and auxiliary contact assembly. It has obtained the applicable certification of T ≠ V.
Use mirror contact to monitor the welding status of main contact of AC contactor by connecting current to components such as safety relay, which can be used as feedback circuit to help build safety circuit.
After sending the command to turn off the excitation coil of the AC contactor, even if the main contact is welded, the auxiliary NC contact must be opened, and it is not allowed to restart.
Applicable standards
The standard products have obtained CCC certification and are marked with CE mark on the product nameplate.
Finger-proof terminal cover
The terminal cover complies with the requirements of machinery safety related to machinery directive EN60204-1 "Protection against direct contact".
Environmental protection
● Materials that comply with the RoHS Directive (EU's Restriction Directive on the Use of Specific Hazardous Substances) and do not contain six substances (or the content is below the specified value) that are restricted by the RoHS Directive.
● Meet the requirements of GB21518
FJ series AC contactors are energy-efficient products that meet the requirements of energy efficiency. Especially FJ-B06, B09, B12, B40, B50, B65, B80 and B95 are energy-saving products with energy efficiency reaching level 2.
