Spreads ABB circuit breakers are a amperometric devices that are responsible for performing the disconnection protection at the time that the system filters a significant enough current to earth. These devices perform constant calculation of the sum of the vectors of streamlines whether or triphasic and single phase, if the result of the sum is zero, is allowed to continue the supply of electricity. If the sum exceeds a any given time the value set by the user, the supply will be interrupted immediately.
ABB circuit breakers which are driven by residual current can be classified according to form detectable wave, depending on the sensitivity of interruption or as downtime.
