The latest in the high voltage range offering enhanced flexibility over the choice of cables, entries, and cable terminations. The 4TJB can accept three-phase connections either straight-through or bottom entry only. The unit can accommodate one connector per phase in and out.
Up to 45kV in Zone 1 Areas.
ATEX Certificate Number : Baseefa09ATEX0186X IECEx Certificate. Number : IECEx BAS 09.0088X.
DTS-01 deluge tested enclosure.
Fault rated 40kA for 1 second.
Enclosure Ratings
* (x-x) demotes the number of connectors per phase, 1st position = top, 2"d position = bottom. For example: 4TJB(1-1) = 1 x conductors per phase top entry and 1 x conductor per phase bottom entry.
Standard Specifications
* where enclosure also has an electrical connections, marking will also include Ex eb marking — Refer to Ex cert for details.
