Prepaid kWh


Prepaid kWh or also known as the kWh token. To find out the power attached to the token, there are several things you should know. Like the CL code listed on the MCB installed on the kWh meter.

The code contains information about how much power is installed on the token you have. The following is the meaning of the CL code from the MCB that is attached to your house token:

  1. CL2= 450 kVA
  2. CL4= 900 kVA
  3. CL6= 1300 kVA
  4. CL10= 2200 kVA
  5. CL16= 3500 kVA

kVA, or the abbreviation of Kilo Volt Ampere, states the unit of power and its active power. There is another way to calculate manually using the CL code on your house token by multiplying the CL code by the base Power (220 kVA). As an example :

The codes or letters on the token each has its own meaning. This meaning provides information on how much power is installed in the house token. If, taking example from the image above, the explanation are as follows:


The known code, CL6, which means 6 A (Amperes) and the number 230/400V 50Hz which means voltage 220 V (Volts). To calculate the electric power of your home token, is to multiply the 6 A electric current by the 220 Volt voltage.


Electrical power -> 6A x 220 V = 1320 VA


Making the token attached to your home's kWh is 1300 VA. From the calculation above, it can be rounded to make it easier to inform.
