c, the operating mechanism is mainly composed of mechanical linkage components, through the push rod can accept each pole contact group short circuit decoupling signal and from the electronic decoupling device overcurrent overload, break shortage of phase, three-phase unbalance, over-voltage under-voltage caused by the breaking signal and make IDCPS-63 free decoupling cut off the fault circuit, the operating mechanism rotating handle in the free decoupling position, the main circuit is disconnected, only after the fault can be removed by the operating Handle rotation to the re-buckling position to reset the closure, you can determine the working status of the product by operating the rotary handle control.

d. Electromagnetic drive mechanism consists of coils, cores, control contacts and standoffs, etc., with the function of receiving control power and operating instructions to control the main contacts to perform the connection or disconnection of the main circuit with under voltage, loss of voltage protection function.

e, the main circuit contact group consists of dynamic, static double-breakpoint contacts, arc extinguishing chamber, current-limiting fast-action mechanism and body shell, each extremely a group, independent of each other, in the event of a short circuit at the load end, the fast-action mechanism quickly move to separate the main contacts to cut off the circuit, and through the short-circuit push rod to make the operating mechanism free to unbutton, while the lever of the operating mechanism to cut off the control coil circuit, so that the coil is de-energized, the main circuit of each phase In the disconnected state, because the main circuit contact group uses advanced current-limiting type fast short-circuit decoupling and superior performance of the arc extinguishing system, so that IDCPS-63 has short-circuit breaking capability.

f, intelligent decoupler mainly by the intelligent control chip, digital tube, electronic components, decoupling coil and action mechanism, in the specified overload conditions with good and reliable protection function: adjustable overload, adjustable overcurrent, three-phase unbalance, over-voltage undervoltage and a series of basic protection functions and has the anti-time characteristics, intelligent decoupler linkage mechanism and the main circuit contact group to achieve perfect coordination between the protected When the fault occurs in the line to be protected, it can act reliably and quickly and break the main electrical apparatus through the top lever touch operation mechanism and control coil circuit to realize the protection function.

g. IDCPS-63 structure adopts inverted design, the contact group contact and interrupting system is at the bottom of the installation surface, the operation mechanism and electromagnetic drive mechanism are at the top of the contact and interrupting system, the contact is divided and closed by the suction and disconnection operation of the armature of the electromagnetic drive mechanism, the operation mechanism can control the main contact of the product contact group through local or remote control of the coil of the electromagnetic drive mechanism to open and close.

5、Installation and use

5.1, IDCPS-63 in the installation should be checked before the operation knob can be operated normally and in the disconnected position, "AUTO" for the main circuit on state, "TPIP" for the decoupling position, this state due to line failure decoupling position, must be The IDCPS-63 can be operated only after the fault is clear to the special administrator, "OFF" is the main circuit disconnect position, "REST" is the re-buckling position, the IDCPS-63 can be reset and re-buckled only if the operating knob is moved to this position.

5.2, IDCPS-63 in the installation before use carefully check whether the coil and accessories power supply voltage is consistent with the product description is consistent with the actual control line to avoid damage IDCPS-63 products.

5.3、When the coil is connected to (85%~110%) Us, the solenoid will be reliably closed when the knob is operated to the "AUTO" position, and the solenoid will be reliably released when the knob is operated to the "OFF" position.

5.4, IDCPS-63 decoupler action current setting value factory set at the maximum, the user can be adjusted according to the actual needs of the panel dip switch.
