SCHNEIDER A9Z51463 Residual Current Circuit Breaker RCCB Type AC 4P 63A 30mA

RCD Circuit Breaker SCHNEIDER A9Z51463 Residual Current Protective Device, RCCB Type AC 4P 63A 30mA
The SCHNEIDER A9Z51463 is an Acti9 iID series Residual Current Circuit Breaker (RCCB), Type B-EV for 3-phase 4P systems, rated at 63 A with a 30 mA tripping sensitivity. It is a premium safety solution engineered to protect against life-threatening risks from all forms of residual leakage currents, including high-intensity smooth DC currents.

Specifications
- Type B-EV Protection: Covers detection of all types of leakage currents, especially smooth DC currents, making it ideal for circuits utilizing inverters or large EV chargers.
- High Current Rating: 63 A rating suitable for circuits carrying high currents in 3-phase systems.
- Wiring: Features double terminals supporting front and rear wiring connections, providing installation flexibility.
- VisiSafe and VisiTrip: Equipped with safety and maintenance convenience features just like other models in the Acti9 iID range.

Applications & Usage

- 3-Phase Electric Vehicle Charging Stations: Used to protect high-power EV chargers (e.g., 22 kW or lower) in commercial buildings, condominiums, or public charging stations.
- 3-Phase Solar Inverter Systems: Used as earth leakage protection devices for large-scale solar power systems connected to the electrical grid.
- VFD Motor Controllers: Used in circuits supplying power to 3-phase motors controlled by Variable Frequency Drives, which may generate DC leakage currents to ground.
