Meets IEC IP65 standard—dust-tight (6) and protected against low-pressure water jets (5). This rating ensures complete protection from solid particles and water ingress, making it suitable for the harshest outdoor hazardous environments. An explosion-proof power distribution box is a specialized electrical enclosure engineered to safely contain internal electrical arcs, sparks, or explosions without allowing them to ignite surrounding flammable gases, vapors, or combustible dust. Each enclosure delivers dependable IP65–IP68 sealing for outdoor and industrial use, with options for plastic waterproof distribution box housings and DIN rail waterproof electrical distribution box. The three most widely accepted explosion-proof certification systems are: Each system has its own markings, classifications, and safety standards that define the type of hazard, how often it occurs, and how equipment must be designed to safely operate in that environment., hazardous. ●Series:SW-MC ●Material:Polycarbonate ●IP Rating:IP65 ●NEMA Rating:4X ●Color:Light Grey ●Application:Outdoor ● SMC material is used for pressingand molding. There are fixed mounting holes at the bottom of the box. This system is. Therefore, type plastic weatherproof electrical box must meet the explosion-proof performance requirements specified in GB3836 standard.
