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.

#1. Solar DC MCB

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.

#8. AC MCB For Solar

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.
