FAQs
Plan for a three-pole, fusible DC disconnect with 100 A capacity and 600 VDC per pole. Verify input/output wiring is In/Out(LC/SR): 1/0-#14 AWG and ensure the enclosure is mounted in a suitable outdoor location. Follow NEC 690 guidelines and UL 1741/UL 98B requirements for safe disconnect operations and coordinated protection with upstream and downstream gear.
The DCG3063FRM provides 100 A amperage rating across three circuits, with a maximum of 600 VDC per pole and fusible protection. It is designed for grounded PV systems, uses an isolated return, and supports In/Out wiring of 1/0-#14 AWG. These features enable reliable fault isolation and compliance with NEC and UL standards for solar installations.
Yes. The unit is housed in a NEMA 3R enclosure with painted galvanized steel, delivering outdoor durability against moisture, dust, and weather exposure. The rugged construction is intended for solar PV sites, carport arrays, and other outdoor DC disconnect applications where safe isolation and environmental protection are essential.
This disconnect aligns with NEC 690 requirements and UL 1741/UL 98B certifications, confirming suitability for solar PV applications and electrical protection. These standards support safe operation, proper coordination with PV arrays, and acceptance by utility and code authorities, reducing project risk and tightening compliance timelines.
The three-pole fusible design, durable NEMA 3R enclosure, and standardized input/output wiring translate to lower maintenance costs through fewer field failures and faster servicing.
