FAQs
Install the DCU1061UWM in a NEMA 4X enclosure using the 304 stainless steel body for outdoor use. Terminate conductors with lug capacity matching #14-#2 AWG (and up to #14-1/0 AWG solid on the return). Maintain proper clearances per the enclosure dimensions (10.22 in depth, 8.76 in width). Ensure the device is rated for 600 VDC per pole and is wired as a single 30 A circuit with non-fusible protection.
The unit is a 30A, 1-circuit, non-fusible DC disconnect with an ungrounded configuration. It supports a maximum system voltage of 600 VDC per pole and a voltage rating of 600 VDC. It is designed for solar PV applications and features a NEMA 4X enclosure in 304 stainless steel for outdoor reliability.
Yes. The DCU1061UWM aligns with NEC 690 requirements per UL 1741 and carries UL 98B recognition. Its NEMA 4X enclosure, 304 stainless steel construction, and non-fusible protection support compliance for outdoor solar installations and ungrounded DC distribution.
This unit is ideal for solar PV applications requiring ungrounded DC distribution with robust outdoor protection. Its 30A, 600 VDC rating, single circuit, and non-fusible design make it suitable for rooftop or ground-mounted PV arrays where weather resistance and easy field wiring are priorities.
Expect reduced maintenance due to the corrosion-resistant 304 stainless steel NEMA 4X enclosure and non-fusible design that minimizes routine replacements. The rugged construction and straightforward lug wiring help lower installation time and downtime, contributing to a favorable total cost of ownership in solar DC protection schemes.
