MCBs provide overload and short-circuit defense, using a thermal tripping device yet don't defend against ground faults. RCBOs integrate the features of RCDs and MCBs, providing both earth-fault and overcurrent protection. Choosing the appropriate tool depends on your certain safety requirements, and there's even more
