Eaton DCG2103UPM DC Disconnect - NEMA 4, 1000 VDC
Part Number: DCG2103UPM
Quick Summary
Eaton heavy duty DC disconnect is designed to safely isolate DC sources in solar PV installations and other 1000 VDC systems. Engineers often struggle with moisture, corrosion, and wiring errors that threaten uptime and safety. This model carries UL 98B and NEC 690 per UL 1741 certifications, with a NEMA 4 enclosure for weather-resistant outdoor or rugged indoor service. Grounded, non-fusible protection plus isolated return ensure predictable fault clearing and safer maintenance. The steel enclosure is painted for durability, and the 2-circuit, 100 A rating supports scalable PV arrays. All configurations align with #14-1/0 AWG lug capacity, simplifying installation and reducing field rework, while a one-year warranty adds peace of mind.

FAQs
For outdoor PV installations, plan for a weather-protected mounting location with adequate clearance around the NEMA 4 enclosure. Ensure mounting is level and follow clearances per product notes. Use only #14-1/0 AWG lugs as specified, maintain proper torque, and verify isolated return grounding to ensure safe fault paths and compliant wiring in 1000 VDC systems.
The 100 A rating and two circuits support mid- to large-scale DC PV strings within a single disconnect, reducing hardware count and simplifying wiring. This configuration facilitates staged PV expansion and easier service; it also aligns with 1000 VDC system requirements while keeping the system within safe operating limits and improving maintenance efficiency.
Yes, the DCG2103UPM supports #14-1/0 AWG lugs with solid returns, enabling flexible conductor termination. The isolated return arrangement helps prevent cross-path faults, while the grounded configuration enhances safety during disconnects and maintenance. Verify lug torque and use the provided catalog notes to select the correct circuit configuration for your installation.
This disconnect is UL 98B and NEC 690 per UL 1741 listed, with NEMA 4 enclosure rating. These certifications ensure compliance for outdoor solar PV installations and high-voltage DC safety, reduce regulatory risk, and support industry-standard verification for reliability, weather resistance, and safe operation in 1000 VDC systems.
Maintenance gains come from a rugged painted steel enclosure, non-fusible protection for straightforward fault tracing, and an isolated return design that minimizes fault propagation. ROI improves through reduced field wiring complexity, fewer components, and a one-year Eaton warranty that lowers lifecycle risk while delivering durable performance in demanding environments.
