Differential current protection, much like a ground-fault interrupter (GFI), measures incoming and exiting current from all three phases, stopping the circuit in case of any imbalance, no matter how long it persists. It is one of the most complex and difficult topics in power system engineering. High voltages and currents, if not properly managed, can lead to system faults, equipment damage, fire hazards, and even fatal accidents. Most basic distribution boxes only adopt single protection device with obvious protection blind spots. The combined. To eliminate safety hazards as fast as possible To limit service outages to the smallest possible segment of the system To protect the consumers' apparatus To protect the system from unnecessary service interruptions and disturbances To disconnect faulted lines, transformers, or other apparatus. After the power enters ip65 stainless steel enclosure from the main power source, it will pass through the main circuit breaker for primary control.
