FAQs
The DH163URKN is well suited for solar PV DC installations and industrial control panels that require a reliable, single-pole DC disconnect. Its 100 A rating and 600 VDC capability support high-current, low-impedance isolation, while the NEMA 3R enclosure protects against weather exposure. This makes it a practical choice for outdoor substations, rooftop arrays, and remote equipment enclosures.
Key specs include 100 A amperage rating, 1 circuit, single-pole configuration, non-fusible protection, 600 VDC voltage rating, and a NEMA 3R enclosure. The unit uses painted galvanized steel for durability and weighs about 22 lb, with compact dimensions suitable for space-limited installations. It is UL Listed for safety compliance.
Yes. The NEMA 3R enclosure and UL Listed certification make it appropriate for outdoor solar DC isolation. Its 600 VDC rating supports PV system standards, and the single-pole, 100 A design provides straightforward, safe disconnection for routine maintenance and fault isolation in outdoor solar arrays.
This model carries UL Listed certification, indicating compliance with recognized safety standards. The enclosure is rated NEMA 3R for weather resistance, enhancing reliability in outdoor environments. Together, these features support procurement requirements and regulatory acceptance in industrial settings and solar installations.
Maintenance requirements are primarily around periodic inspection of enclosure integrity and electrical connections; the non-fusible design reduces spares and wiring complexity. ROI benefits come from reduced maintenance downtime, faster installation due to factory-installed neutral assemblies, and longer equipment life due to robust enclosure protection, especially in outdoor, high-dust, or corrosive environments.
