| Plug-in Boxes (PIB)
- Available in 32A,63A & 100A ratings.
- These are compact sheet-steel boxes with hinged-doors housing the fuse-holders,which are solidly connected to high conductivity copper clip-on contacts reinforced by spring steel strips.These clipon contacts plug directly on to the busbars at the plug-in points.For additional safety two earth-pins are located at the two eds of these boxes.While inserting these boxes into the plug-in points,the earth pins engage first in the special earth bushes provided on the underside of the busbar chamber before the main contacts make. While withdrawing these boxes, the earth connection is maintained even after the main contacts are isolated.
