1.General
1.1 Function
Control electric circuits.
Protect people against indirect contacts and additionalprotection against direct contacts.Protect installations against fire hazard due to insulationfaults.
Residual current circuit breakers are used in housing, tertiarysector and industry.
1.2 Selection
Detectable wave form
Type B
Tripping is ensured for sinusoidal AC residual currents pulsedDC residual currents, alternating residual sinusoidal currentsup to 1000Hz, pulsating direct residual currents and forsmooth direct residual currents, whether applied suddenly orincreasing slowly.
Tripping sensitivity
30mA - additional protection against direct contact
100mA - co-ordinated with the earth system according tothe formula IAn < 50/R, to provide protection against indirectcontacts;
300mA - protection against indirect contacts, as well as firehazard.
Tripping timeInstantaneous
It ensures instantaneous tripping (without time-delay)
1.3 Approvals and certificatesCE, KEMA
1.4 Add-on devices
