Product Q&A

Q:Is this HA-4 distribution box specifically optimized for outdoor solar PV systems?

Yes. The HA-4 enclosure is engineered specifically to serve as a combiner or switch box for outdoor solar photovoltaic installations. Its high UV resistance prevents material degradation under direct sunlight, and its IP65 ingress protection safeguards solar DC circuit breakers or isolators against rain, dew, and ambient moisture.

Q:What is the maximum capacity of circuit breakers this box can accommodate?

The HA-4 model features an integrated standard 35mm DIN rail that can comfortably accommodate up to 4 standard single-pole miniature circuit breakers (MCBs) or a combination of double-pole breakers, RCBOs, or surge protectors depending on your specific circuit configuration.

Q:How does the PVC/ABS material compare to metal enclosures in coastal environments?

Unlike metal enclosures that are highly susceptible to rust and salt-spray oxidation over time, this high-grade PVC/ABS plastic box is 100% corrosion-proof. It offers absolute resistance to chemical vapors, salt-spray coastal air, and acidic rain, making it a much longer-lasting and cost-effective solution for maritime or highly corrosive industrial sites.

Q:Does the enclosure come with pre-drilled cable entry holes?

The enclosure comes with precision-engineered, pre-molded knockouts on both the top and bottom surfaces. These allow technicians to easily remove the exact sized ports needed for PG or metric waterproof cable glands during installation, ensuring a tight, uncompromised seal without the need for manual drilling tools.
