DEHN Enclosure for Equipotential Bonding
Enclosure System for SPDs protecting IT Equipment
- Premounted enclosure system for wiring and protection components
- Tested lightning impulse current carrying capacity
- Optimised for equipotential bonding (surge arresters and shield connection)
- Lockable metal enclosure to prevent against unauthorised access
Description
Lightning current carrying enclosure with IP 40 degree of protection for different distribution board designs and for the insertion of surge arresters. The cover can be removed from the wall plate without tools and features a lock with cylinder quarter turn and a key. The C-shaped design of the wall plate allows side and front access during installation work. LSA mounting frames or DIN rails can be mounted on the wall plate with cable entry plates and cable rails.
Despite a high packing density, structured cable management is ensured – crossing of cables with wires is avoided and the cables of e.g. the LSA blocks are clearly structured due to the 30 mm grid dimensions. For this kind of cabling, an optional shield connection system is available (constant force spring). The well-conceived earthing system permanently connects all conductive components of the enclosure system to the earthing block via mechanical contact or earthing conductors.

Detail 1
DEHN enclosures for equipotential bonding (DPG) come in different sizes, allowing the insertion of 3/6/12/22 LSA blocks. Even if 20/50/100/200 pairs are connected, enough space is provided for the earthing plug for inserting the earth drain wires.
Detail 2
All equipotential bonding conductors are led together in the central earthing block.
Detail 3
The shields of incoming lines can be contacted with SA KRF constant force springs in a space-saving and lightning-current-carrying way.
Detail 4
The enclosure for equipotential bonding can be locked (key supplied with the enclosure).
