@@prabhatsingh5377 TNC switch is ok.. no closing command comming from electric circuit but it takes automatically open close command after spring motor charged.. i seen same thing ABB ACB some time it took automatically open close command after spring motor charged some time it charge in 1st try even electric power supply off and breaker charge through manually push button.
We lubricant the jaw contact to protect from corrosion in certain atmospheres and for jaw contact lycon grease has the Ability to regulate the flow of current while remaining inert to the surge, good anti-corrosion and anti-wear properties and high surface tension to avoid migration are some of the desired properties of good electrical contact
Dear mani thanks for the comment and sorry for the late reply due to my bussy schedule i was not able to reaply. If you want to rack in and rack out the ACB first of all you need to trip the circuit breaker ( you have to off the circuit breaker ) never rack out the circuit breaker when it is connected with the load because when it is connected to load and you rack out the ACB there will be sparking in the jaw contact There will be Electrical hazard so be always safe To rack out and rack in the ACB its HAS so simple Step just first of all you have to lock The trip latch . After that take the rack out handle and insert it in the rack out / rack in spring hole and than rotate the handle anticlockwise the ACB Will get rack out Same you have to do while racking inside the ACB Feeders Hope you understand how to rack in and rack out I hope you have subscribed my TH-cam channel
Unbelievable, you should never use pressurized solvents like WD40 to clean the contacts or mechanism! PLEASE read manufacturer maintenance instructions first...
+amit thapa mgr agar acb mechanical haldle sae charge nai hoa raha tha first usko open kar sabhi mechanical parts ko dekho . ki kahi koi bolt to missing nai hai ya phir koi parts damage to nai hai usmai

Some times breaker automatically on while motorized spring charge done. Why this happened can you explain me...
Is same problem exist in test position also ? . Check TNC Switch

Not all ABB breaker or not all L&T breaker but rare case of breaker... It might be some internal problem..
why using lycon grease in jaw contact
We lubricant the jaw contact to protect from corrosion in certain atmospheres and for jaw contact lycon grease has the Ability to regulate the flow of current while remaining inert to the surge, good anti-corrosion and anti-wear properties and high surface tension to avoid migration are some of the desired properties of good electrical contact
Please tell me sir rack out After breaker closing procedures

There will be Electrical hazard so be always safe
To rack out and rack in the ACB
its HAS so simple Step just first of all you have to lock The trip latch .
After that take the rack out handle and insert it in the rack out / rack in spring hole and than rotate the handle anticlockwise the ACB Will get rack out
Same you have to do while racking inside the ACB Feeders
Hope you understand how to rack in and rack out
I hope you have subscribed my TH-cam channel
Electrical Technician thank you sir rack out after manuvaley closing which one removed
Please upload a video in ACB which motor are used
Unbelievable, you should never use pressurized solvents like WD40 to clean the contacts or mechanism! PLEASE read manufacturer maintenance instructions first...

Please don't ad music
how inter lock 2 breaker
Use other breaker NC contact in series with closing circuit . So that if one breaker ON then other breaker cant ON
Music is soo annoying 😢
Apka number sir

Bad engineering. The design and layout should have been made much more user friendly.
Ye kya cheej ka sound hai sir ji machine ya breaker ye part ke baare me bol kar btaya kro na ya phir youtube me videos dalna band kar do
