Eaton heavy-duty DC disconnect DCG6064FXM - NEMA 4X 600 VDC
Part Number: DCG6064FXM
Quick Summary
Eaton heavy-duty DC disconnect DCG6064FXM provides robust 200 A DC isolation for solar PV systems. Engineers often struggle with equipment that overheats or complicates safe shutdown during PV maintenance. UL 98B and NEC 690 per UL 1741 approvals, plus a NEMA 4X-rated enclosure and 316 stainless steel construction, underpin long-term reliability in harsh environments. This six-pole, grounded disconnect is designed for isolated return configurations and accommodates large main lugs with LC and SR terminations, simplifying installation and service. By combining rugged protection with clear wiring paths, it helps reduce downtime, improve safety, and support compliance-driven purchasing for industrial and utility-scale solar projects. It also aligns with industry best practices for modular, scalable PV protection.

Feature: The DCG6064FXM is rated for 200 A, enabling it to safely interrupt full PV array current without supplementary switching gear. Business Impact: This capacity reduces equipment counts, simplifies protection schemes, and lowers ownership costs by limiting components that can fail. Application: Ideal for mid- to large-scale solar installations where a single, rugged DC disconnect at the array interface consolidates protection, isolation, and serviceability while meeting 600 VDC system requirements. Feature: Six-pole configuration with fusible protection and an isolated return delivers precise fault isolation and safer maintenance. Business Impact: The design minimizes backfeed risk and improves uptime by allowing selective disconnection of subcircuits. Application: PV DC systems requiring coordinated shutoff across multiple conductors, with each pole protected by a fusible element for predictable clearing during fault events. Feature: NEMA 4X-rated enclosure constructed from 316 stainless steel provides excellent weather resistance and corrosion protection. Business Impact: Outdoor and harsh indoor environments see extended service life, reducing unscheduled downtime and maintenance cost. Application: Roof-mounted, ground-mounted, and exposed installations in industrial settings where enclosure integrity is critical to system reliability. Feature: Main lug capacity of In/Out(LC) 300 kcmil-#6 and In/Out(SR) 300 kcmil-#6 supports large conductors and seamless field terminations. Business Impact: Streamlines wiring, improves electrical performance, and decreases labor time during installation and future maintenance. Application: DC PV strings and combiner layouts that require robust, high-current connections with minimal voltage drop. Feature: Broad certifications and ratings including UL 98B, NEC 690 per UL 1741, and NEMA 4X with grounded, isolated-return operation. Business Impact: Helps with regulatory compliance, safety audits, and customer acceptance in utility or commercial solar projects. Application: Retrofit and new-build solar projects across industrial, commercial, and utility sectors seeking proven protection for DC photovoltaic systems.
