MR8880 HIOKI Memory HiCorder Application Note

PublishTime：2021-10-29

Residual Current Circuit Breaker (RCCB) is a device containing a mechanical switch to disconnect a circuit when it detects a current difference between the live and the neutral wire^[1]. Under normal condition, the current in the live wire and the returning current from the neutral wire is the same^[2]. The current difference, called Residual Current, is often caused by leakage current (mostly due to old or damaged insulation of equipment) flowing to the ground through a conductive path such as a human body. The Residual Current is used to disconnect the circuit in the RCCB according to their residual current rating design. Figure 1.0 shows the components of a RCCB while Figure 2.0 shows the pole types, residual current trip sensitivity rating, and type of RCCB available in the market.
