FAQs
The DCU3063UPM supports up to 100A across three circuits in an ungrounded DC setup, with main lug connections suitable for #14-1/0 AWG conductors. It is designed for solar PV applications and provides a straightforward, scalable solution for mounting in limited spaces while maintaining safe isolation.
This unit is designed to meet PV safety requirements, including NEC 690 per UL 1741 and UL 98B. It is built to function reliably in outdoor environments and supports compliance for solar protection solutions in commercial and utility-scale projects.
Yes. The enclosure is NEMA 4 rated and made from painted galvanized steel, offering weatherproof protection against moisture, dust, and other environmental factors. This makes it well-suited for outdoor solar PV installations and other harsh environments.
Plan for three circuits with 100A capacity and use conductors up to #14-1/0 AWG for both lug and solid return connections. The unit dimensions are 10.22 in depth, 16.13 in width, and 24.95 in height, with an approximate weight of 30 lb, aiding site planning and transport.
Eaton provides a standard warranty of one year from installation or 18 months from shipment, whichever comes first. The non-fusible design reduces internal maintenance, while the rugged enclosure minimizes environmental wear, supporting long-term reliability in solar and other DC protection applications.
