1. Product Overview
The PZ30 series distribution box is a widely used modular electrical enclosure designed for organizing and protecting low-voltage circuit breakers (MCBs), RCDs, and other control components in residential, commercial, and light industrial applications. Built with high-quality ABS plastic, these boxes are available in both surface-mount and flush-mount versions, with a range of sizes from 2-way to 36-way to suit different distribution needs.
The transparent blue cover allows quick visual inspection of circuit status, while the robust housing provides protection against dust, accidental contact, and minor environmental factors. PZ30 boxes are the standard solution for indoor power distribution panels, offering a safe, neat, and cost-effective way to organize electrical circuits.
2. Key Features
- Surface or Flush Mount Options: Suitable for both exposed and recessed installation in walls or cabinets.
- Wide Range of Sizes: Available in 2, 4, 6, 8, 10, 12, 16, 20, 24, 32, and 36-way configurations.
- Durable ABS Construction: Flame-retardant, impact-resistant plastic for long service life.
- Transparent Protective Cover: Allows visual inspection of breakers without opening the box.
- DIN Rail Compatibility: Standard internal DIN rail for easy installation of modular components.
- Safe & Organized Design: Provides protection against accidental contact with live parts and keeps wiring neat.
- Easy Installation: Pre-punched mounting holes and simple assembly process for quick setup.
- Versatile Application: Ideal for home distribution panels, office power boards, and small commercial installations.

3. Working Principle
The PZ30 distribution box acts as a central hub for low-voltage electrical circuits:
- Organization: MCBs, RCDs, and other modular components are mounted on the internal DIN rail.
- Protection: The enclosure protects components from dust, accidental contact, and minor mechanical damage.
- Inspection: The transparent cover allows users to quickly identify which breakers are on/off without opening the box.
- Safety: The box’s insulated construction prevents electric shock hazards from live parts.
4. Applications
- Residential Power Distribution: Home main panels, room sub-panels, and apartment electrical boards.
- Commercial Buildings: Offices, retail stores, and small shops requiring organized circuit distribution.
- Light Industrial: Workshops, garages, and small factories for power control circuits.
- Renovation & Construction: New builds and retrofits needing a cost-effective distribution solution.
- DIY Electrical Projects: Safe and organized enclosures for custom control and power systems.
5. Installation Instructions
- Choose the Right Location: Install the box in a dry, well-ventilated indoor area, away from direct sunlight and moisture.
- Mounting:
- Surface Mount: Secure the box to the wall using the pre-drilled mounting holes.
- Flush Mount: Cut a recess in the wall to fit the box, then secure it in place.
- DIN Rail Setup: Install the 35mm DIN rail inside the box (included with most models).
- Component Installation: Snap MCBs/RCDs onto the DIN rail and wire them according to your circuit diagram.
- Final Check: Close the transparent cover and ensure all components are securely installed before energizing the system.
6. FAQ
Q1: What’s the difference between surface mount and flush mount?
- Surface mount: The box sits on top of the wall, making installation quick and easy, ideal for retrofits.
- Flush mount: The box is recessed into the wall for a clean, built-in look, common in new construction.
Q2: How do I choose the right size (number of ways)?
Count the total number of circuit breakers you plan to install (including main and branch breakers) and add 10–20% extra for future expansion. For example, if you need 8 breakers, choose a 10-way or 12-way box.
Q3: Can I use this box outdoors?
No, the PZ30 series has an IP30 rating, designed for indoor use only. For outdoor applications, use a weatherproof enclosure with a higher IP rating (IP65+).
Q4: What does “way” mean in distribution boxes?
A “way” refers to the number of standard 18mm modular slots the box can accommodate, typically for one single-pole MCB.
Q5: Is the PZ30 box flame-retardant?
Yes, the ABS plastic used is flame-retardant, providing an extra layer of safety against electrical fires.
