Product Description
1. General
1.1 Function
-Control electric circuits.
-Protect people against indirect contacts and additional protection against direct contacts.
-Protect installations against fire hazard due to insulation faults.
-Residual current circuit breakers are used in housing, tertiary sector and industry.
1.2 Selection
Detectable wave form
-AC class :Tripping is ensured for slowly increasing sinusoidal AC residual currents.
-A class :Tripping is ensured for sinusoidal AC residual currents and for pulsed DC residual currents, whether applied suddenly or increasing slowly.
Tripping sensitivity
10mA - precision instrument leakage protection and bathroom use.
30mA - additional protection against direct contact.
300mA - protection against indirect contacts, as well as fire hazard.
Tripping time
Instantaneous
It ensures instantaneous tripping (without time-delay).
