The earth-fault circuit breakers are of the electromechanical type. They are available in 2 Pole and 4 Pole versions type B detects all types of fault currents; pure alternating current and smoothed, pulsating and pure direct current. Even mixed frequencies up to 1 MHz are detected and broken in the event of a fault in a reliable manner. With rated fault current 30mA and 300mA. All can be provided with an auxiliary contact to indicate that the earth fault circuit breaker has tripped.
