Square D VH323N - 100A, 240V, Fused Disconnect Switch

The Square D VH323N is a rugged 100A, 240V fused disconnect switch engineered for industrial and commercial environments where safe electrical isolation is non‑negotiable. Designed to support lockout/tagout procedures, it provides dependable disconnection under load, helping teams work safely during maintenance and service while safeguarding equipment and personnel over the long term.

Key features that matter in the real world

• 100A amperage rating and 240V voltage rating for reliable, on‑line isolation of standard industrial circuits.
• Fused disconnect switch design offers built‑in overcurrent protection alongside a clear disconnection path, reducing the risk of arc flash and electrical mishaps during maintenance.
• Lockout/tagout readiness support ensures compliant-energy isolation during service, improving worker safety and site compliance.
• Durable, long‑lasting performance built to withstand demanding industrial environments while delivering consistent operation when it matters most.

Ideal use cases

• Motor control centers and main service disconnects in manufacturing, processing, and packaging facilities.
• Maintenance shutdowns for pumps, compressors, conveyors, HVAC equipment, and other heavy‑duty machinery.
• Temporary isolation points in electrical distribution for safe troubleshooting and repairs.
• Equipment retrofit or upgrades where a reliable, fuse‑based isolation path enhances overall system safety.

Why this fused disconnect stands out

The VH323N goes beyond a basic disconnect by integrating fusing into the isolation path, delivering immediate protection against overcurrent while guaranteeing a solid, visible disconnect under load. This combination is especially valuable in environments where equipment uptime and safety are equally critical. With Square D’s reputation for dependable electrical components, the VH323N delivers predictable performance that you can count on during routine maintenance and emergency work alike.

Practical considerations and tips

• Verify circuit compatibility: ensure your installation aligns with the VH323N’s 100A, 240V specifications for optimal performance.
• Plan for lockout/tagout: pair the VH323N with standard lockout hardware to streamline safe maintenance procedures.
• Schedule routine inspections: periodically check fuse integrity and the switch mechanism to maintain reliable disconnection under load.
• Integrate into preventive maintenance plans: use as a clear, designated isolation point to minimize downtime during service tasks.
