PZ30 series combined terminal distribution box (hereinafter referred to as: the distribution box), conform to the standard GB7251.1 and JB/T7121 modular terminal combination electric appliance etc. Distribution box adopts steel model structure in the form of case base adopts steel structure and plating, end cover made and flame retardant engineering plastics injection molding with transparent polycarbonate protective cover. Distribution box is both plastic artistic aesthetic feeling, and have a strong steel structure, transparent cover made one switch electrical appliances working condition However. Electrical components adopt guide installation of power distribution box, element width for 9 mm module. Layout reasonable, compact installation, disassembly, maintenance is very convenient. According to user needs to make a small circuit breaker, a beautiful, hao hua, high strength, resistance to impact the distribution box. 2. The overview: PZ30 modular terminal combination electric appliance is a device for installing terminal apparatus, its main characteristic is to use modular electrical size, installation rail contour artistic, the use of safe, has been widely used at home and abroad. 3. The scope of use: PZ30 terminal combination electric appliance is suitable for the rated voltage 220 v or 220 v, total electrical load flow is not more than 100 a single-phase three-wire or three-phase circuit, at the end of five line as to control electric equipment, to overload, short circuit, overvoltage and a complete set of device for leakage protection. Can be widely used in high-rise buildings, hotels, residential, stations, ports, airports, hospitals, cinemas and theatres, large commercial outlets, and industrial and mining enterprises, etc. Four main structure features: terminal combination electric main structure parts are transparent cover, cover, box, installation rail, rail height adjusting screw, conductive row, convenient cover and electric switch components, etc. Built-in electric switch components adopt width 9 mm module of electric equipment, installed on the hat shape orbit, can according to need any combination, installation height adjustable orbit, especially for dark outfit type is more convenient. Disassembling handle convenient, quickly switch components, electric and other part of the inside cover to cover, open the door easily operation, the use of safe and reliable, behind the body up and down, left and right sides and are set into a round hole, then in the wiring. 5: other security: ark type is indoor enclosed distribution cabinets, using special profile packaged structure, adopt the thickness of 1.2 mm cold rolled steel sheet, with light weight, high strength, etc. Plastic door with fire retardant resin materials, can effectively prevent the fire spreading. Built-in electrical components adopt width to 18 mm module of electric equipment, installed on the standard guide. Can use any combination, easy to tear open outfit, handle the leakage switch component, electrically charged part covered inside the cover, open the door for easy operation. Protection: prevent leakage, electric shock, short circuit, overload and other protection device. Into the method of line: body up and down or so and can be set on the back into the line struck down hole, convenient connection. Protection: the door is with multiple strands of soft braided wire connected to the PE in the point, the whole body structure to form the continuous protection circuit. Structure: cabinet put oneself in another's surface using epoxy powder electrostatic spraying, uniform appearance for corrosion protection, strong adhesion, good texture, appearance give a person feel comfortable, galvanizing technology on internal structure, has certain corrosion resistance ability.

Structural characteristics of
1, mature technology: PZ30 distribution box, simple principle, group components: all kinds of switch components, shell, transparent door, cover, zero rows, protective earthing, insulated wires, etc.
2, security, ark type is indoor enclosed distribution cabinets, using special profile packaged structure, adopt the thickness of 1.2 mm cold rolled steel sheet, with light weight, high strength, etc. Plastic door with fire retardant resin materials, can effectively prevent the fire spreading. Built-in electrical components adopt width to 18 mm module of electric equipment, installed on the standard guide. Can use any combination, easy to tear open outfit, handle the leakage switch component, electrically charged part covered inside the cover, open the door for easy operation.
3, have prevent leakage, electric shock, short circuit, overload and other protection device.
4, into the line: body up and down or so and can be set on the back into the line struck down hole, convenient connection.
More than 5, the door is to use stock soft braided wire connected to the PE in the point, the whole body structure to form the continuous protection circuit.
6, cabinet put oneself in another's surface using epoxy powder electrostatic spraying, uniform appearance for corrosion protection, strong adhesion, good texture, appearance give a person feel comfortable, galvanizing technology on internal structure, have certain ability of corrosion resistance.
7, ark components adopt quality distinguished old brand low-voltage electrical appliances at home and abroad. The product has good stability.
8, the assembly is excellent: we have a group of professional assembly workers. Skilled, skills, solid foundation.
