Q1. What is the primary application of the PZ30 Series Lighting Box?
A: The PZ30 is a modular terminal distribution box designed for AC 50Hz, rated voltage 220V or 380V. It is primarily used for lighting distribution, power control, and circuit protection (overload and short-circuit) in modern buildings, hotels, and residential complexes.
Q2. How many modules can a standard PZ30 enclosure accommodate?
A: The PZ30 is highly flexible. We offer various sizes ranging from 4 units to 72 units (18mm per module). Common configurations include single-row (up to 20 units), double-row, and triple-row designs to fit different circuit densities.
Q3. What materials are used for the PZ30 enclosure and door?
A: We offer two versions:
Metal Version: High-quality cold-rolled steel with an electrostatic powder coating for superior durability.
Plastic Version: High-strength, flame-retardant ABS or PC material, which is lightweight and aesthetically pleasing for indoor residential use.
Q4. Is the PZ30 suitable for both flush and surface mounting?
A: Yes. Our PZ30 boxes are designed for versatility. You can choose the Flush-mounted (embedded) version for a clean, hidden look in walls, or the Surface-mounted (wall-mount) version for easy installation on existing structures.
Q5. What are the Ingress Protection (IP) ratings for the PZ30 series?
A: The standard rating for indoor residential use is IP30. For areas requiring higher protection, such as kitchens or sheltered outdoor corridors, we can provide customized versions up to IP40 with enhanced door seals.
Q6. Does the PZ30 include the internal DIN rail for component mounting?
A: Absolutely. Every PZ30 box comes equipped with a standard 35mm DIN rail. The internal structure is designed with adjustable depth, allowing you to easily mount MCBs (Miniature Circuit Breakers), RCDs, and timers from any international brand.
Q7. How do you ensure electrical safety and earthing in the metal boxes?
A: Safety is our priority. Our metal PZ30 boxes feature a dedicated copper earthing terminal (PE) and a neutral busbar (N). The door and the frame are connected via a flexible grounding wire to ensure complete electrical continuity and user safety.
Q8. What is the flame-retardant rating of the plastic components?
A: The plastic covers and internal components of our PZ30 series meet the UL94-V0 or V1 flame-retardant standards. They are tested for glow-wire resistance at 650°C to 960°C to ensure they do not support combustion in the event of an electrical fault.
Q9. Can the door opening direction be changed?
A: Most of our PZ30 models feature a reversible door design. This allows the transparent or solid door to be installed to open from either the left or the right, providing maximum flexibility during on-site installation in tight spaces.
Q10. Does your factory in Shanxi provide OEM or custom labeling?
A: Yes, as a direct manufacturer, we offer OEM services. We can customize the box color (standard RAL 7035), add your company logo, and provide professional English circuit labeling kits to help your brand stand out in your local market.
