• Standard: -20° to +40°C (-4° to 104°F)
• Option: -50° to +65°C (-58° to 149°F)

Junction Box Specification

* (x‐x) demotes the number of connectors per phase, 1st position = top, 2nd position = bottom. For example: HVJB73(2‐1) = 2 x conductors per phase top entry and 1 x conductor per phase bottom entry. ** Power rating is determined by ambient temp range: ‐20 to +400C / ‐50 to +550C respectively. The higher power rating can also be achieved if the enclosure is marked Ex e IIC T1500C Gb. *** For cables greater then 300mm2, it is advisable to use the HVJB8 size enclosure.
