mini RCBO | Residual Current Operated Circuit Breaker with over-current protection

VRL02 Mini RCBO

(MCB sized 1 module with switched neutral)

1. General

1.1 Function

VRL02B RCBO type B and VRL02B+ RCBO type B+ are appearance design, compact structure, good reliability, and high safety. They are universal residual current circuit breaker with Overcurrent protection(RCBO).

Rated current up to 63A and for purposes of residual current protection, overcurrent (overload) and short circuit protection. When any personal electric shock occurs or the circuit leakage current exceeds the predetermined value, the RCBO can automatically cut off the power supply in a very short period of time, so that the safety of persons and electrical equipment can be operated.

Residual current circuit breaker with Overcurrent protection(RCBO) 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 with Overcurrent protection(RCBO) 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.
