A non-polarity DC mini circuit breaker (MCB) is a type of circuit breaker designed for use in direct current (DC) electrical systems. It is called non-polarity because it does not have a specific polarity (positive or negative) designation like some other DC components.
This type of circuit breaker is used to protect electrical equipment and wiring in DC circuits from overcurrents and short circuits. It typically has a compact design, making it suitable for use in applications where space is limited.
Non-polarity DC mini circuit breakers can be reset manually after they trip, and they are available in a range of current ratings and trip curves to suit various applications. They are commonly used in automotive, marine, and renewable energy applications, among others.
