The DC MCB (Miniature Circuit Breaker) is a solar protection device that protects our electrical equipment from overloads and short-circuits. They are designed to protect the electric circuits and other appliances by automatically tripping in no time when an abnormal current is detected.
Miniature circuit breakers are classified into two types: DC MCB and AC MCB. Both types of MCBs are further distinguished by their current carrying capacity like 16A, 25A, 32A, 40A, 63A & 125A.
If the current exceeds the device’s rated current carrying capacity, it interrupts the flow of electric current by breaking the circuit and protects your appliances from overload and short-circuits.
A DC miniature circuit breaker is a small but important part of any solar system. This small solar protection device is used to protect devices that operate on direct current (DC) power, like solar panels and solar batteries.
DC MCB can sense when the current (Ampere) coming from the solar panels exceeds a certain threshold. In the event of overcurrent, it will trip automatically and protect the DC appliances/components as well as DC circuit from damage.
Kenbrook Solar offers a complete range of MCB for solar at very affordable prices. You can see and compare the prices below.

An AC MCB is a type of miniature circuit breaker that is designed to protect our sensitive appliances and electrical circuits that run on alternative current (AC). These small solar protection devices can be used everywhere, whether it is a residential place or a commercial place.
Just like DC MCBs, it senses the increase of amperes in AC power supply. When the current supply exceeds the rated capacity of a MCB, it trips automatically to protect your electrical appliances and circuits from overload/short-circuit.
There are various models in solar AC MCBs also. You can see the best possible prices of AC MCBs below.
| AC MCB Model | Selling Price | Buy It Now |
| 32A Sigma AC MCB (1Ph- 2 Pole) | Rs. 309 | |
| 40A Sigma AC MCB (1Ph- 2 Pole) | Rs. 389 | |
| 32A Sigma AC MCB (3Ph- 4 Pole) | Rs. 665 | |
| 63A Sigma AC MCB (3Ph- 4 Pole) | Rs. 975 | |
The right size for the DC MCB is determined considering the current range of the circuit where the device is needed to be installed. To provide you with an idea, mentioned below is the table of most suitable MCB rating for a range of current.
| Current Range | Most Suitable MCB Rating |
0A – 12.5A | 16 AMP MCB |
13A – 20A | 25 AMP MCB |
21A – 25.5A | 32 AMP MCB |
26A – 32A | 40 AMP MCB |
33A – 50.5A | 63 AMP MCB |
