What are the types of DC circuit breaker?

DC circuit breakers are commonly available in several types, including Miniature Circuit Breakers (MCBs), Molded Case Circuit Breakers (MCCBs) designed specifically for DC applications, and Type B Residual Current Devices (RCDs). These circuit breakers are used to provide protection for various types of DC circuits, including individual loads and primary circuits in applications such as solar PV arrays, battery banks, and inverters.
