Stand-alone B type Ex9LB63 residual current circuit breakers suitable for EV Chargers
These RCCBs are suitable for various domestic as well as industrial applications, where frequency inverters, PV plant, EV chargers and similar elements are used. B type provides a sensitivity to residual AC, pulsating and smooth DC current, together with high frequencies up to 1 kHz.
An important advantage of Ex9LB63 is that it is based on electronic technology that allows more accurate measuring of residual current and, as a consequence, reduction of unwanted tripping. These devices also do not suffer from magnetization of the tripping unit.
