An RCCB (residual current circuit breaker) for an EV charger is a safety device that is specifically designed for use with electric vehicle charging systems. It is used to protect against electrical fires and shocks caused by overcurrent, short circuits, and earth leakage. The RCCB is typically installed between the EV charger and the electrical distribution panel of a home or commercial building, and is designed to automatically disconnect the charger in the event of an electrical fault. It is an important component of any EV charging system, as it helps to ensure the safety of the charger and the vehicle being charged. The RCCB is typically designed to be compatible with various types of EV chargers, including Level 1, Level 2, and Level 3 chargers.

Type B RCCBs,
|
in addition to normal AC, can detect high frequency AC and pure DC earth leakage currents. Reducing the risk of fire
and/or electrocution through 4h automatic disconnection of the electrical supply relies on the selection of the correct type of RCCB. |

2.Application Example:
|
EV & PV installations, Frequency converters, UPS installations, High-frequency power converters, Building site power supply
cabinets. |
|
3.Function
|
3.1 Control electric circuits.
3.2 Protect people against indirect contact and additional protection against direct contact. 3.3Protect installations against fire hazard due to insulation faults. Residual current circuit breakers are used in housing, tertiary sector and industry. |
