      What protective devices are required for EV Chargers?

      Protective devices which are required for EV chargers can be either RCBO or MCB+RCCB. 

      For 1P 16A  => 3,7Kw load    protection devices = 20A curve C + type B 30mA ( A9F54220 + A9Z51240)
      For 1P 32A  => 7Kw load       protection devices = 40A curve C + type B 30mA  ( A9F54240 + A9Z51240)
      For 3P 16A  => 11Kw load     protection devices = 20A curve C + type B 30mA  ( A9F54420 + A9Z51440)
      For 3P 32A  => 22Kw load     protection devices = 40A curve C + type B 30mA  ( A9F54440 + A9Z51440)

      The circuit breaker value (20A or 40A) depends on the cable size, length and environmental parameters (up to the electrician)

      Do you have a 20A single phase contactor?

      Yes the part number is 4CTN1

      Looking for a 10mA 20A RCBO.

       Part code is 4RCBE220/10

      Can a 5.0P or 5.0H trip unit be used for ground fault alarm without tripping?

      Product Line:
      Circuit Breakers

      Electrical Distribution Equipment.

      Yes. To have ground-fault alarm without tripping, add a programmable contact module (M2C or M6C), and program the trip unit for alarm.
      Neither the 5.0 nor 5.0A trip units can be used because those trip units do not have the required programming functionality.
      If replacing a standard trip unit (not A, P or H), the 12-pin connector for the trip unit (kit S33101 for Masterpact, S33100 for Powerpact) must also be ordered.
