VKL11 RCCB Type B+

1. General

1.1 Function

A residual current circuit breaker (RCCB) is an electrical device that is designed to protect against electrical shock caused by ground faults. It works by detecting any imbalance in the electrical current flowing through a circuit and immediately shutting off the power to prevent any potential injury or damage. RCCBs are particularly important in areas where water and electricity are in close proximity, such as bathrooms and kitchens. They are also commonly used to provide additional safety protection in damp or wet locations, as well as in industrial settings where high voltage or high current circuits are used. Overall, RCCBs provide a crucial layer of protection against electrical hazards and are an essential component of any safe and effective electrical system.

VKL11B RCCB and VKL111B+ 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.
