Improved ADO to Screw terminal blocks with fuse holder
are now available. ABB Entrelec type D4/8.S...ADO
replaces the old range type D4/8.S...ADO.
The critical difference in the two designs is the
direction the fuse holder rotates when it opens. The
legacy design fuse holder rotates upward towards the ADO
connection, and the new design rotates downward toward
the screw terminal connection.
View illustration.
In most applications this small change provides a
significantly safer installation.
