Square D H223 - 100A, 2-Pole, Fused Disconnect Switch

Meet the Square D H223, a rugged 100A, 2-pole fused disconnect switch built for demanding industrial and commercial environments. This unit delivers safe electrical isolation and dependable disconnection under load, making lockout/tagout procedures straightforward and reliable while supporting long-term durability in harsh service conditions.

Why the Square D H223 Stands Out

• Integrated fused protection: The 100A fused design provides immediate, reliable interruption of current during faults, helping protect wiring and connected equipment.
• Two-pole isolation: Independent breaking of both live conductors ensures complete circuit isolation for safer maintenance and safer startup sequences.
• Lockout/Tagout readiness: Built to accommodate padlocks and safety tags, facilitating compliant and safer plant maintenance workflows.
• Industrial-grade durability: Engineered to endure the rigors of demanding environments, with construction suited for long service life inside electrical enclosures.
• Maintenance-friendly design: Replaceable fuses enable straightforward field servicing with minimal downtime, keeping downtime and maintenance costs lower over the life of the system.
