It is suitable for usage in grid connection and wind turbines in on shore and off shore environment.  Supporting a wide application range, it represents a branching point for all cross‑sections from 25 to 300 mm2. The overall dimensions are compact and designed to take up the minimum space. Full metal encapsulation gives reliable and insured service.

MV Junction box provides ability to connect all Raychem screened separable connectors type RSTI, Coupling Connectors RSTI-CC and Surge Arresters RSTI-CC-SA. This gives easy accessibility to the capacitive test points for determining whether the circuit is energized and opportunity to protect equipment from overvoltages. Possibility to monitor and detect the voltage gives reliability and safeness in its function within electrical system.
Standards: Tested according to the cable accessories standard CENELEC HD 629.1 S2, which includes BS, VDE and other international specifications. With fulfilment of IP66 test degree of protection with integrated bottom plate, MVJB is completely secured against water and dust ingress.
