DAB7LN-40 series DPN Residual Current Operation Circuit Breaker(RCBO)
DAB7LN -40 residual current circuit breakers are small devices designed with high breaking capacity (6kA) and they are suitable for the disconnection of neutral lines. The circuit breakers are widely used in AC50H low-voltage electrical systems with a rated voltage of 230V and rated current of no more than 40A. This effectively protects people from electric shock and circuit equipment form overcurrent or short circuiting.
