Note
• The assembly kit must be ordered as individual components (enclosure base,
covers, 2 x intermediate frames, 2 x 3KE switch disconnectors and required
assembly kit).
• The switches must be connected using copper busbars or NYA cables.
• The "break-before-make" version of the changeover contact is supplied.

1) Values in brackets apply to parallel switches. For thermal reasons the rated
operational current is reduced to approximately 80 % of the rated current.
2) The "break-before-make" version of the changeover contact is supplied. If
the "make-before-break" version is required, a "-Z" must be added to the
Order No. and "make-before-break" specified in plain text.
