The earth fault circuit breakers are of electromechanical type and work without external voltage sources. They come in 2P and 4P design, class A, with rated current 30mA and 300mA in:
- Standard design
- Asi which is short-term delayed 10mS and has elevated 3kA surge current resistance. They are even supplied with inner protection which makes them suitable for humid and aggressive environments. All can be equipped with help contact for indicating that the earth fault circuit breaker has tripped.
