High immunity RCCB TYPE B 63A Residual Current Circuit Breaker
1. General
1.1 Function
Type B RCCBs (Residual Current Circuit Breakers) are primarily used for protecting against pulsating DC residual currents, high-frequency AC residual currents, and smooth DC residual currents in specific applications such as charging electric vehicles and renewable energy sources. They are also used in installations where there is a possibility of smooth DC residual currents, for example, IT networks and UPS systems.
Type B+ RCCBs (Residual Current Circuit Breakers) are mainly used in applications where high-frequency and high-pulse DC residual currents are present, such as photovoltaic (PV) generators, electric vehicles, battery systems, and welding equipment. The Type B+ RCCBs offer additional protection against DC residual currents compared to standard Type B RCCBs.
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)
