With a 200A rating and a 600V capacity, this 3‑Pole device delivers dependable disconnection even under load, helping you maintain safety and continuity in your electrical systems.\u003c\/p\u003e \u003cp\u003eDesigned to support proper lockout\/tagout procedures, the H364 safeguards maintenance personnel by providing a clear, verifiable isolation point. When service work is necessary, you can lock the switch in the off position and tag it to prevent accidental re-energization, reducing risk and downtime across uptime-critical environments.\u003c\/p\u003e \u003cp\u003eKey to its reliability is the fused design, which offers built‑in overload protection for three‑phase circuits. This means less wear on downstream equipment and a more predictable protection strategy for motors, feeders, and other heavy loads. The enclosure features a NEMA 1 rating, making it suitable for indoor, dry locations where dust and incidental moisture are manageable, while supporting long‑term durability in busy facilities.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eProduct highlights at a glance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 200A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVoltage rating:\u003c\/strong\u003e 600V\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePoles:\u003c\/strong\u003e 3‑Pole\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eEnclosure:\u003c\/strong\u003e NEMA 1 (indoor, dry locations)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Fused Disconnect Switch\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eBrand\/model:\u003c\/strong\u003e Square D H364\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eWhy choose the Square D H364?\u003c\/strong\u003e This fused disconnect is purpose-built for reliability in environments where safe maintenance shutdowns, clear isolation points, and durable performance matter most.
