Conformity to the Low Voltage Directive in the EU (Continued)
11. Use wires listed in EN60204 Appendix C.
MCCB: Moulded case circuit breaker
RDC: Residual-current-operated protective device
ELCB: Earth leakage circuit breaker
Notes 1) A box (
) in the above table replaces E suffix for filtered version.
*1 The frame size and model of the MCCB or RCD/ELCB (with the exception of those exclusively
designed for protection from ground faults) will vary, depending on the power transformer capacity.
Refer to the related technical documentation for details.
*2 The recommended wire size for main circuits is for the 70qC 600V PVC wires used at an ambient
temperature of 40qC.
*3 Wire sizes are calculated on the basis of the input current under the condition that the power supply
capacity and impedance are 500 kVA and 5%, respectively.
