Eaton Specification Sheet - DH163UDKN
Feature: 100 A, single-pole, single-throw operation delivers clean, mechanical isolation with minimal components. Business Impact: Reduces failure points, accelerates maintenance, and lowers lifecycle costs by simplifying switchgear inventories. Application: Suitable for DC distribution panels, battery storage, and PV inverters where fast, reliable isolation is required.
Feature: Non-fusible configuration with factory-installed neutral assemblies. Business Impact: Enhances safety and reduces in-field wiring errors, enabling consistent control references across circuits. Application: Ideal for DC control circuits requiring a solid isolation point with neutral continuity.
Feature: NEMA 12 enclosure in painted galvanized steel. Business Impact: Provides robust protection against dust, grime, and incidental moisture, reducing enclosure-related outages. Application: Appropriate for industrial plants, manufacturing floors, and outdoor-adjacent panels.
Feature: 600 VDC rating and UL Listed certification. Business Impact: Supports regulatory compliance and safe operation in high-voltage DC systems, lowering risk during maintenance. Application: Solar PV installations, battery storage, and DC distribution networks.
Feature: 20 at 250 Vdc capability and compact dimensions (10.22 in x 24.95 in x 11.79 in) with 26 lb weight. Business Impact: Facilitates easy mounting, inventory planning, and faster installation with minimal space impact. Application: Retrofit or new-build control panels where space and weight are considerations.
Feature: Fuse configuration described as Non-fusible. Business Impact: Clarifies that protection is provided via external fusing per system design, reducing unintended fuse interactions. Application: Systems that require downstream or upstream fusing while preserving simple isolation at the disconnect.

FAQs
Installation begins with standard safety procedures: power off the panel, verify voltage ratings, and mount the unit in a compliant enclosure with appropriate clearance. Connect the neutral assemblies as factory-installed, route conductors per manufacturer guidelines, and ensure the disconnect is fully seated in its mounting. Use proper torque on mounting hardware and verify UL compliance during commissioning.
The DH163UDKN is a 100 A, single-pole, single-throw DC disconnect with a 600 VDC rating. It is non-fusible by design and is UL Listed for safety. It provides a single isolation point per circuit and supports 1 circuit in a NEMA 12 enclosure, suitable for industrial DC distribution and PV/battery applications.
Yes. The device is UL Listed, rated for 600 VDC, and housed in a NEMA 12 enclosure, which makes it appropriate for solar PV DC isolation in challenging environments. Its 100 A rating supports typical PV array combiner or DC distribution segment isolation, while its neutral assemblies simplify system wiring where reference points are needed.
The DH163UDKN utilizes a NEMA 12 enclosure constructed from painted galvanized steel. This provides protection against dust and moisture in industrial settings, enabling reliable operation on factory floors or in outdoor-adjacent panels where splash or grime exposure is a concern.
Eaton provides a warranty policy aligned with policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first.
