Explosion-proof box for PSBL, PSB, MSB and HSB systems
Explosion-proof box for PSBL, PSB, MSB and HSB systems
Explosion-proof boxes manufactured by Bartec are used for switching power cables with heating circuits of various electric cable heating systems. By electrical systems we mean self-regulating heating cables of the PSBL, PSB, MSB and HSB types.
Features box:
Wide usable temperature range
Can be combined with PLEXO connection technology, heat shrink and cold technology
Incombustibility
Shock resistance
Approval of the system
Up to three heating circuits can be connected to the supply voltage inside the junction box.
