The doors can be folded to 90º and 180º, with two anchorage
points and a fastening pin for the open positions to prevent
them from being unexpectedly closed.
Furthermore, the medium voltage switchgear can be
ordered with a locking device for the medium voltage cable
input in the bottom part of the enclosure. It has up to three
one-core cable inputs, with a maximum diameter of 50 mm.
