This pack includes:
- 1 AT WGB Type B RCD - 1P+N - 63A - 30mA
- 1 Schneider thermal-magnetic circuit breaker 1P+N - 40A - Curve C
Type B Electrical Protection Pack for 7 kW single-phase charging station
The following electrical protections must be installed on a dedicated circuit.
Protections to be installed for a single-phase connection for a 7 kW wallbox without internal 6mA DC leakage protection:
- 63A RCD - Type B - 1P+N - 30mA
- 40A circuit breaker Curve C
1/ Type B single-phase RCD
The Type B RCD - 1P+N - 63A - 30mA is essential for any charging station installation.
It compares the incoming current with the outgoing current and cuts off the circuit if the difference exceeds 30mA. This function protects people against electric shocks.
It must be paired with a circuit breaker.
Installation
It must be installed on a line dedicated specifically to the charging station, after the main RCD of the electrical panel.
The charging station must have its own dedicated line, with its own circuit breaker and its own RCD.
Main characteristics
- Type: B
- Poles: 1P+N
- Rated current: 63A max
- Rated residual current: 30mA
2/ Schneider 40A circuit breaker
The Schneider thermal-magnetic circuit breaker 1P+N - 40A - Curve C is essential for any charging station installation. It protects the installation against overcurrents and short circuits.
Its Curve C is suitable for high-current devices such as charging stations. Its high breaking capacity and fast tripping ensure safety, reliability, and long service life.
Compatibility
This circuit breaker is suitable for a charging station set between 6A and 32A.
It must be paired with an RCD (it is compatible with the AT WGB RCD).
Installation
It must be installed in the electrical panel, on the RCD dedicated to the charging station. The charging station must have its own dedicated line, with its own circuit breaker and its own RCD.
Main characteristics
- Number of poles: 1P+N
- Supply: 230V
- Breaking current: 40A
- Breaking capacity: 4.5-6kA
Dedicated Line and Mandatory Electrical Protections
Single-phase installation:
- Residual current device: Type B, 30mA, 2P or 1P+N, max. 63A (a Type A, F or Hpi is sufficient, instead of Type B, if the charging station is equipped with a DC leakage current detector)
- Circuit breaker: Minimum Curve C, minimum breaking capacity 3kA, 2P or 1P+N, 16 to 40A (choose 3 to 8A more than the rated current of the charging station)
Three-phase installation:
- Residual current device: Type B, 30mA, 4P, max. 63A (a Type A, F or Hpi is sufficient, instead of Type B, if the charging station is equipped with a DC leakage current detector)
- Circuit breaker: Minimum Curve C, minimum breaking capacity 3kA, 4P or 3P+N, 16 to 40A (choose 3 to 8A more than the rated current of the charging station)
Cable cross-sections for connections, according to French standards NF C15-100 and NF C15-722:
- Wallbox charging station 16A or 16A socket, cable length less than 100m: cable cross-section 2.5mm²
- Wallbox charging station 32A, cable length less than 100m: cable cross-section 10mm²
Overview of cable cross-sections for connections (NF C15-100 and NF C15-722):
| Rated current | Circuit breaker rating | Minimum cross-section | |
| Charging station or socket | 16A | 20A | 2.5mm² |
| Charging station | 32A | 40A | 10mm² |
| Charging station | 63A | 80A | 16mm² |
