Control electric circuits.
Protect people against indirect contacts and additional
protection against direct contacts.
Protect installations against fire hazard due to insulation
Residual current circuit breakers are used in housing, tertiary
sector and industry.
Detectable wave form
Tripping is ensured for slowly increasing sinusoidal AC
Tripping is ensured for sinusoidal AC residual currents and
for pulsed DC residual currents, whether applied suddenly
or increasing slowly.
30mA - additional protection against direct contact.
300mA - protection against indirect contacts, as well as fire
It ensures instantaneous tripping (without time-delay)
