MOBS
Mechanical Only Breakdown Systems (MOBS)
MOBS is a physical termination for NE Passively Safe Columns. It is a minimum option for isolating the electricity supply to a single structure under impact. The system’s activation relies on the physical disconnection on impact of a tethered in-line IP68 Plug and Socket. It can also be used as a local isolation point.
The MOBS unit is housed within an IP67 enclosure and mounted in an underground STAKKAbox™ Access Chamber.
