Earth Leakage Molded Case Breakers offer superior Class 1 ground fault protection and improved ground fault coordination capability. Earth leakage ground fault protection differs from other types of systems in its level of sensitivity. The sensitivity of traditional devices is limited by the cumulative error of the residual current sensors and the placement of the phase and neutral conductors inside the current sensor. Earth leakage breakers and motor protectors are zero sequence sensing devices. They are factory supplied with a single sensor and ground fault relay built in. This technique allows for protection sensitivities down to the 30 milliampere level.
