This is a 63A three-phase power splitter with 3x 63A/400V input and 4 CEE 3x 32A/400V output.
Each output is protected by a 32A multi9 circuit breaker and each phase can be read out by a 4-digit voltimeter as well as 4-digit ammeter. Furthermore, a residual current circuit breacker is used for protection against electronic shock under fault conditions.
