MCB CALCULATOR BREAKER SIZE CALCULATOR LCETED lceted LCETED
To calculate circuit breaker and wire size: Write down an approximation of the total load you will connect to the circuit breaker.; Get a circuit breaker rated for 125% of this load.; Make sure the wire it will be paired with has a higher ampacity than the circuit breaker's rating. Otherwise, the current may heat the wire above safety levels under normal operation.

The MCB type is best suited for domestic appliances, where the average current load, type C. MCB Type C trips when the current flow is 5-10 times more than normal.Type D MCBs have high durability as they can withstand up to 10-20 times the current rate.If you are looking for a circuit breaker for a device with a high starting load such as a motor, then type D is the ideal choice.

PF=Power factor. V=Line voltage. E=The efficiency of the motor. Keep in mind that this circuit breaker sizing only considers motor overload, which happens when the operation of a motor (in excess of its normal, full-load rating) persists for a long enough time that it damages or overheats the motor. When specifying motor circuits, engineers.

1 HP = 746 Watt. 746 / (220 x 0.95) = 3.56. So it's will take is starting time double current 3.56 x 2 = 7.12. So the suitable size of electric cable is 2.5 mm according table 1. So Our Total load is 52 Amps, so the suitable size of RCD circuit breaker is 63 Amps and double pole main circuit breaker is also 63 amps.

An MCB is an automatically operated electrical switch. Miniature circuit breakers are intended to prevent damage to an electrical circuit as a result of excess current. They are designed to trip during an overload or short circuit to protect against electrical faults and equipment failure. MCBs are widely used as isolating components in.

1) Ampere Rating ( In ) Formula : In = Iz + (0.25 x Iz) In = ampere rating Iz = Load ampere. Calculation : In = 20 ampere + (0.25 x 20 ampere) In = 25 ampere@ 32 ampere. * in market we cannot found 25 ampere of MCB,so we can used 32 ampere for our application. Refer the ampere rated in technical data for MCB from manufacture.
