40A three-phase differential switch - compatible with all three phase charging stations
The circuit breaker HAGER CDB440F - Type B - 3P+N - 40A - 30mA is essential for any installation of charging station.
It will compare the input current with the output, and turn off the circuit if the difference is greater than 30mA. This function protects people against electric shock.
It was selected by a team of skilled electricians to be compatible with all single-phase charging stations of our site.
This differential CDB440F switch is compatible with all three phase charging stations of the market that have a load current between 1 and 32A, even those that are not equipped with a continuous leakage current detector DC.
If your charging station is already equipped with a continuous leakage current detector DC, then a three-phase differential type A (eg, HAGER BDH440F ), less expensive is sufficient.
It must be coupled to a circuit breaker, and is compatible with all types of circuit breakers HAGER NGN , NGT, NFT, NRN or NSN.
It must be installed on a line specifically dedicated to the charge port after the main breaker of the electrical panel.
The charging station must have its own dedicated line, with its own circuit breaker and its own differential switch.
It must be associated with a type of circuit breaker HAGER NGN.
