Square D H223N - 100A, 2-Pole, Fused Disconnect Switch

When reliability and safety are non-negotiable in industrial electrical systems, the Square D H223N delivers trustworthy isolation with simplicity. This 100A, 2-Pole Fused Disconnect Switch is designed to provide a clean, lockable disconnect that keeps maintenance teams safe during servicing and ensures equipment is fully isolated from power when needed.

Key advantages

• 100 Ampere rating for dependable control of medium-power circuits, from motors to control panels.
• 2-Pole design delivers simultaneous disconnection of both live conductors, reducing shock risk and ensuring thorough isolation.
• Fused disconnect adds overcurrent protection at the source, limiting fault energy and protecting wiring and devices downstream.
• NEMA 1 enclosure suitable for indoor, non-weatherproof environments, offering a compact, solid housing.
• Lockout/Tagout compatibility supports standard safety procedures to prevent accidental re-energization during maintenance.
• Durable, long-term performance from a trusted Square D product designed for industrial and commercial use.

Who is this for?

The Square D H223N is ideal for facilities that require robust electrical isolation for service and maintenance tasks. Use it in manufacturing lines, HVAC control circuits, machine rooms, or any panel where a reliable disconnect is essential.

Why choose the Square D H223N?

Unlike basic switches, the H223N combines a fused protection element with a dedicated disconnect, providing immediate fault interruption and clear power-off status. The two-pole arrangement ensures safe, thorough isolation of both conductors, making it a preferred choice for systems where uptime and safety matter.

Use cases and practicality

• Equipment maintenance and repair workflows that require lockout/tagout safeguards.
• Power isolation for routine testing, calibration, or preventive maintenance on motor circuits and control panels.
• As a service disconnect in commercial or light industrial installations where code compliance and reliability are critical.
