PZ30 distribution box
The PZ30 series is used as a terminal combination type distribution box with a rated operating voltage of AC380/220V. The box body is made of cold-rolled steel plate, the base is made of steel structure and plated, the plastic panel is made of environmental protection and heat resistant material, all metal parts have corrosion resistance, and the conductive row support is all flame retardant insulation material. The electrical components in the distribution box are equipped with guideway, which can be flexibly assembled, arranged in a compact and reasonable way. Installation, dismantling and maintenance are all very convenient, and the technology is mature and the appearance is beautiful. It is suitable for high-rise buildings, houses, stations and hospitals and other places. PZ30 distribution box conforms to GB7251.3-2006 "low voltage switchgear and control equipment" and other standards.
◇Main features:
●The surface of PZ30 is made of epoxy powder electrostatic spray, which is uniform and beautiful, which is good for anti-corrosion, strong adhesion and good texture. The internal structure is galvanized and has certain anticorrosive capability.
●The box below can be set into the line of the knock off holes, convenient wiring.
●The internal electrical components are all with 18mm modulus of width, which are installed on the standard guide rail. The user can assemble arbitrarily according to the need, disassemble and disassemble easily, the handle of the switch element is exposed, the charged part is covered in the upper cover, and the door can be opened for convenience.
