RCBO | Residual Current Operated Circuit Breaker with over-current protection
VRL02 Residual Current Operated Circuit Breaker with over-current protection
(MCB sized 1 module with switched neutral)
1. General
VRL02 residual current operated circuit breakers are suitable for lines with AC 50/60Hz, rated voltage 240V, rated current up to 50A and for purposes of residual current protection, overload and short circuit protection. When any personal electric shock occurs or the circuit leakage current exceeds the predetermined value, the residual current operated circuit breaker 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. The residual current operated circuit breaker can be used for infrequent conversion of lines under normal conditions, and applied under occasions such as industrial, and commercial, high-rise buildings and residential houses.
