Industrial Switch Socket Change Over Contactor 50 Amp 80 Amp





As it is known, when the capacitor starts to operate, they cause a high frequency between 1~15kHz. And a current that is 180time higher than rated current for very short time period. Shock inductance is to be fixed to each phase to limit this current. But practically this type of operation is difficult. That's why capacitor switching contactors are used and for this reason the life-time of contactors increase 100% in comparision with normal contactor. Example: if electrical life of normal contactor is 100,000times in max load, electrical life of capacitor switching contactor is 200,000times.

While Switching on a capacitive circuit, a high frequency (1...15kHz) and large transient current Peaks are produced. Switching of capacitor for a single or one of the capacitor banks are different from each other. Step by step "switching on" operation is more difficult for contactor than capacitor bank. Because during this operation for capacitor bank, compensated current occurs. For this reason selecting of a suitable contactors the compensating current must be take into consideration for 50kVAr and above, and for less than 50kVAr can be ommitted.


Operating Principle: When coil of contactor is energized, first contact of passing block is closed, starting current of contactor is passed through this contact, approximately after 3-5 ms contacts of passing blocks are opened and rated current of contactor is carried on main contacts.

Operation Condition:


1. When the switch is closed condenser must be discharged before recharged.

(Maximum residual voltage at terminals ≤ 50V)


2. In working voltage 500V (Ue=500V), 100,000 times for UKC1(D)-9C~40C and 80,000 times for UKC(D)1-50C~85C


3. To prevent short current, gG type Fuse must be 1.5~2 times than rated current.


4. It must be separated from resistant wire


5. The average temperature over a 24-hour period, in accordance with standards IEC70 and 831 is 45 degree
