Tripping sensitivity
30mA - additional protection against direct contact.
100mA - co-ordinated with the earth system according to the formula lan <50/R,to provide protection against indirect contacts;
300mA - protection against indirect contacts,as well as fire harzard.
Tripping time
Instantaneous
It ensures instantaneous tripping (without time -delay).
