FAQs
The DCG1105UXM is a single-circuit, non-fusible DC disconnect housed in a 316 stainless steel NEMA 4X enclosure. Its dimensions (57.5 in L x 27.5 in W x 12.38 in H) and weight (116.5 lb) inform mounting clearances and shade considerations. Ensure proper grounding, isolated return wiring, and UL-listed connections, and verify compatibility with your system’s 1000 VDC rating and site environmental conditions.
Key specs include a 400 A amperage rating, 1000 VDC maximum voltage/rating, non-fusible protection, grounded system with isolated return, and single circuit configuration. Confirm UL listing status and enclosure integrity (NEMA 4X, 316 stainless steel) to ensure reliability under outdoor conditions and washdown requirements.
Yes. The unit’s 316 stainless steel construction, NEMA 4X enclosure, and UL Listing are specifically chosen for outdoor, washdown, and corrosive environments typical of solar PV sites. It provides durable DC isolation for PV arrays while maintaining safe operation in exposed locations.
The DCG1105UXM is UL Listed and housed in a NEMA 4X enclosure made of 316 stainless steel, offering corrosion resistance and weatherproof protection. Its non-fusible design with grounded, isolated return supports standard electrical safety practices and easier compliance with solar electrical codes.
The rugged stainless-steel enclosure resists corrosion and ingress, reducing maintenance intervals in outdoor PV installations. With a simple non-fusible design and isolated return, fault diagnostics are more straightforward, lowering service time. The combination of UL listing and durable materials contributes to longer system uptime and predictable lifecycle costs.
