FAQs
The DCU1101UPM supports #14-#2 AWG lug capacity and solid returns, enabling direct connections to typical PV conductors. It is rated 30A and 1000 VDC, with a single ungrounded, non-fusible circuit, making it straightforward to integrate into most solar DC paths while meeting NEC 690 requirements.
Plan for a single-circuit harness in a NEMA 4 painted galvanized steel enclosure, suitable for outdoor or damp indoor environments. The unit weighs 21 lb and measures 10.22 in (depth) by 14.14 in (height) by 8.76 in (width). Ensure appropriate mounting clearances and reference the dimension tables for exact ampere-rating configurations.
Yes. The DCU1101UPM is rated for 1000 VDC, designed for DC photovoltaic applications, and features a non-fusible, ungrounded configuration. Its UL 98B and NEC 690 per UL 1741 certifications provide regulatory confidence for high-voltage PV installations.
The unit carries UL 98B and NEC 690 per UL 1741, confirming compliance with recognized electrical safety standards. It is housed in a NEMA 4 enclosure for weather resistance, and its 1000 VDC rating aligns with modern solar arrays, supporting safe installation in industrial environments.
The non-fusible, single-circuit design reduces field-fuse maintenance, while the NEMA 4 enclosure and 1000 VDC rating minimize environmental and high-voltage concerns. The unit includes a one-year warranty (or 18 months from shipment) and straightforward lugs, which lowers downtime, simplifies replacements, and supports predictable total cost of ownership in solar deployments.
