Super immunity RCCB TYPE B
1. General
1.1 Function
VKL11B RCCB and VKL11B+ RCCB is appearance design, compact
structure, good reliability, and high safety. They are universal
residual current circuit breaker.
Residual current circuit breaker type B are suitable for domestic
as well as industrial applications, where are used frequency
inverters, PV plant, EV chargers and similar elements. B type
provides a sensitivity to residual AC, pulsating and smooth DC
current, together with high frequencies up to 1 kHz.
Residual current circuit breaker type B+ meet full type B feature ,
with additional tripping values are defined up to 20KHZ and they
are below 420mA.
They are based on electronic technology, which brings advantages of
more accurate measuring of residual current and, as a consequence,
reduction of unwanted tripping. These devices also do not suffer
with magnetization of the tripping unit.
1.2 Selection
Detectable wave form
Type B 
Tripping is ensured for sinusoidal AC residual currents pulsed DC
residual currents, alternating residual sinusoidal currents up to
1000Hz, pulsating direct residual currents and for smooth direct
residual currents, whether applied suddenly or increasing slowly.
Type B+
Meet full type B feature , with additional tripping values are
defined up to 20KHZ and they are below 420mA
Tripping sensitivity
30mA - additional protection against direct contact.
100mA - co-ordinated with the earth system according to the formula
IΔn＜50/R, to provide protection against indirect contacts;
300mA - protection against indirect contacts, as well as fire
hazard.
Tripping time
Instantaneous It ensures instantaneous tripping(without time-delay).
Short time delay
Selective (time delay)
