Great video. Why is this information so hard to find? It seems like basic stuff that everyone should know who is setting foot in a utility room.

[@user-bp7ro1jb1h]

Brilliant explanation on how to use the MCCB'S adjustable settings.

Need Video on Contactor and its accessories

[@aadedeelectric]

Good job..Thank you for sharing

[@Raja97596]

Good presentation!!
It's very useful.
Pls clarify the difference of Instantaneous and Short circuit

[@henrysroberts1128]

Thanks so much for educating me in this video, but I will like to learn more about electricity can you help me am new to so many things?

[@sidharthsooraj4809]

How calculate the MCCB currernt if 400A breaker its is the sum of three phases or each phase can connect to 80% of 400 A?

[@themeengineers1671]

Every phase is rated at 400amps my friend. Overcurrent at any phase will trigger a trip. Using an trip unit you will be able to better check which is the errant phase.

[@saifullahmushtaq4628]

Sir I have ha MCCB (Main breaker in MDB) rated as below:
MCCB NSx400S
400AT 3P
415V AC schneider
now my system voltage level is 127V/220V.Can i use the above MCCB.
THANKS

[@themeengineers1671]

Hi do check out the rated voltage. It'll affect the max ssc the breaker can handle. It should be no problem

[@stella5600]

Hello can i check if all mccb comes with a electronic trip unit?

[@themeengineers1671]

Hello, there are different trip unit available. Some are thermal magnetic and not electronic. So the answer is no. So depending on your site requirement you may choose different trip units.

[@leoescudero1916]

What is Icw??? Great video, saludos desde Argentina!

[@themeengineers1671]

It is for utilization A breakers and lv switchgears. Usually it is the maximum short circuit withstand current rated up to a certain time. Usually 1 second or 3 seconds. Examples are 85kA 1 seconds, or 50kA 3seconds. Mucha gracias pal.

[@ammarashker5721]

Is it possible to disable the mccb breaker (to stay always on) easily?

[@themeengineers1671]

Depending on the model, you might be able to off the protection with electronic trip units. In your case i would suggest using a switch disconnector. Much cheaper and always at the status u left it. However there will not be any protection

[@ahmedazm4956]

Is the function of ICS &ICU dedicated to the MCCB's only?

[@themeengineers1671]

It is for all circuit breakers in accordance to iec60947-2

[@parmpalsingh1935]

Sir how to select ka value ?

[@themeengineers1671]

Hi it depends on your system requirement. Usually we size from the transformera

[@rahulkharva553]

Sir how I calculate fault level of suitable mccb?

[@themeengineers1671]

Using schneider ecostruxure power design software

[@simonchan7127]

Are you from Singapore?

[@themeengineers1671]

Yes sir :) life is on.
