MCB, MCCB,

-
Hello everyone....
Today i am gonna share you some information about MCB And MCCB this are very common items which are used in daily electrical industrial work. so it's very important to know how all they work in real work.

 WHAT IS MCB?

 An MCB (Miniature Circuit Breaker) operates as automatic switch that opens in the event of excessive current flowing through the circuit and once the circuit returns to normal, it can be reclosed without any manual replacement.

Application and Used of MCB :

  1. Short circuit
  2. Over current
  3. Over load
Select proper MCB according to your load. The availbale size is 6 to 100 amps.

WHAT IS MCCB?

Moulded Case Circuit Breaker is known as MCCB. Rated current upto 1000 amps.

  • The main difference between MCB and MCCB is with the MCB rated under 100 amps with an interrupting rating of under 18,000 amps. Consequently, their trip characteristics may not be adjusted since they basically cater to low circuits.

  • On the other hand, an MCCB comes with an adjustable trip characteristic for the higher models.

This two items are very common anywhere in electrical work. The connections are also easy and installation is easy.

we just have to take care of load amp.

How to use powerflex 4m  VFD : -                                            This is front view of power flex 4m allen-bradly vfd. This vfd generally used up to 0.2 K.W (0.25 H.P) TO 11 K.W (15 H.P). choose your use of vfd by different catlog no. in this model of vfd.  (Note- choose proper vfd. check the voltage and kw rating otherwise the vfd can be hazardous) Installation : - This model of allen bradly is easy to install. behind the vfd there is arrangement to adjust it on C-channel in panel. so its easy to install. First i would suggest to install proper size of MCB to supply the vfd. Check the proper voltage level for supply. Give all the phase to L1, L2 L3 respectively on the top of VFD. Supply on the power and turn on the VFD. Check the VFD and after that i would suggest to connect the motor. Use the manual of powerflex ...

WHAT IS POWER FACTOR? HOW MUCH IT REQUIRED?

Hello everyone... Today we gonna discuss something which is very important in industrial topic. Every Electrical engineer needs to be very conscious about this. WHAT IS POWER FACTOR? HOW MUCH IT REQUIRED?😅 Now all of you know that every industry required to maintain as possible as 0.99 pf . but most of the engineers are not aware what is the required KVAR to reach or to make 0.99 pf. so here i am gonna share something which will show how to and what are the requirement. What is power factor?           "In ac circuits power factor is the ration of real power to apparent power"            "In dc circuits power factor is unity because reactive power absorbed by any inductive circuit is zero. so power factor is unity"  Now most of the of us are working with already installed plant or industries so we don't know what is KVAR rating we need to maintain our power factor at 0.99.  from google image ...

                                 Variable frequency drives Hello guys...  Today i will share some basic  information about variable frequency drive (VFD). →WHAT IS VFD? vfd is nothing but variable frequency drive. it's device to control the induction motor's speed and torque mainly. by varying voltage and frequency of motor speed and torque can be adjustable in electro-mechanical combination. but there are many more use of vfd. (  VFD ; also termed  adjustable-frequency drive , “variable-voltage/variable-frequency (VVVF) drive”,  variable speed drive ,  AC drive ,  micro drive  or  inverter  drive ) VFDs are made in a number of different low- and medium-voltage  AC-AC  and DC-AC topologies                                 ...
