Insulation circuit breakers | Choosing the Right Circuit Breaker
Differential devices measure current flowing in a loop and are therefore tripped if they detect any discrepancy between an incoming and outgoing current. As such, a differential circuit breaker will be activated by discrepancies that might be close to zero and which might typically be caused by high impedance faults such as inefficient insulation that might not be detected by other types of devices.  They are commonly used for protecting generators and...
