FAQs
This unit is designed for standard enclosure integration in industrial DC power distributions. Ensure sufficient clearance for 1500 VDC insulation, mount within compatible enclosures (NEMA 12/3R rated), and align mounting holes with common panel layouts. Check that the overall dimensions (width, height, depth) fit your cabinet footprint and that you observe proper lockout/tagout procedures during installation.
Key specs include a 200 A amperage rating, 1500 VDC voltage rating, single 1‑circuit configuration, and non-fusible protection. Safety features center on robust isolation with minimal arc energy, UL Listed certification for compliance, and a NEMA 12/3R enclosure for durable protection in tough environments.
Yes. The 1500 VDC, 200 A, 1‑circuit, non‑fusible design is well suited for solar PV strings, energy storage modules, and standalone DC distribution trunks in manufacturing facilities. Its UL Listing and rugged NEMA enclosure help ensure safe operation in outdoor or harsh indoor conditions, while maintaining straightforward integration with DC protection schemes.
The primary certification is UL Listed, indicating compliance with recognized safety standards. The enclosure carries a NEMA 12/3R rating, offering dust, oil, and water resistance suitable for industrial environments. The device is designed for 1500 VDC systems and non‑fusible protection, aligning with common industrial and energy storage safety practices.
The non‑fusible, single‑circuit design reduces maintenance complexity and fault handling, while UL Listing and a durable galvanized enclosure decrease replacement and service costs. The unit’s robust construction minimizes downtime in high‑duty DC networks for solar, storage, and factories, delivering a favorable total cost of ownership and faster return on investment.
