Eaton DH223NDK - 100A, 240V, 2-Pole, Disconnect Switch

The Eaton DH223NDK is a purpose-built disconnect switch designed to deliver safe, reliable electrical isolation in demanding industrial and commercial environments. With a 100A rating and 240V operation, this 2-pole isolator ensures both live conductors can be independently and securely disconnected, making it an essential component for maintenance, service, and shutdown procedures.

Built for long-term durability, the DH223NDK excels where reliability matters most. Its NEMA 1 enclosure is suited for indoor installations in control panels, service rooms, and equipment housings, providing solid protection against dust and minor contaminants while keeping critical connections accessible for quick disconnection when needed. This makes it an ideal solution for motor feeders, HVAC systems, manufacturing lines, and other industrial or commercial circuits that require dependable isolation under load.

Key features and benefits

• 100A amperage rating – handles typical load disconnections for medium-duty equipment with confidence.
• 240V operation – compatible with common two-hot-leg electrical systems in industrial and commercial settings.
• 2-Pole design – ensures simultaneous disconnection of both live conductors for complete isolation of the circuit.
• NEMA 1 enclosure – indoor protection that helps keep switches protected in standard plant environments.
• Lockout/tagout readiness – facilitates safe maintenance by allowing proper isolation and tagging to prevent accidental energization.
• Designed for durability – built to perform reliably over years of service in busy electrical rooms and panels.

Who will benefit

Facility managers, maintenance technicians, and electrical contractors working in factories, warehouses, data centers with indoor switchgear, or commercial buildings will appreciate the DH223NDK for its straightforward protection and dependable performance. It’s particularly well-suited for equipment that requires a clear, verifiable disconnect point during servicing, preventive maintenance, or emergency shutdowns.
