Square D H223N - 100A, 240V, Fused Safety Switch

The Square D H223N is a high-performance fused safety switch engineered for industrial and commercial environments where safe, reliable electrical isolation is non‑negotiable. Designed to support lockout/tagout procedures and provide dependable disconnection under load, this 100A, 240V safety switch is built for long-term durability in demanding settings.

Why the H223N stands out

• Precise electrical isolation: trusted to fully isolate circuits when service or maintenance is required, helping protect personnel and equipment.
• Fused protection: integrates fast-acting fusing to guard downstream equipment from overcurrent events while enabling a clean disconnect.
• Lockout/Tagout compatibility: designed to streamline safety procedures, making it straightforward to secure a circuit during maintenance.
• Under-load disconnection: engineered to reliably interrupt the circuit even when it’s energized, reducing the risk of arcing and ensuring safer shutdowns.
• Durable industrial build: rugged enough for vibrant commercial facilities and tougher environments, delivering dependable performance over time.

Ideal applications

• Motor control circuits and equipment that require a clear, guarded disconnect up to 100A at 240V
• Manufacturing lines, conveyors, pumps, and HVAC systems where safe maintenance shutdowns are essential
• Service entrance points and machine rooms needing reliable isolation and compliance with safety protocols

How it works

With the H223N, disconnection is deliberate and verified. The fused safety switch provides a defined, mechanically robust disconnect point, enhancing protection during service, while the integrated fusing remains in place to guard against overload conditions. This combination supports compliant lockout/tagout practices and helps ensure that circuits stay de-energized during maintenance.
